What is a Welding Glove?

What is a Welding Glove?A welding glove is personal protective equipment used to protect the operator’s hands during welding operations against high heat, sparks, splashes of molten metal, mechanical impacts, and electrical risks.Since the risks that occur during welding directly affect the hands and wrist parts, the correct usege of welding gloves has critical importance for both occupational safety and work efficiency.Functions of Welding GlovesA welding glove does not only provide protection; it also affects welding performance:Provides protection against high temperaturesProvides protection against high temperaturesOffers resistance to mechanical impactsImproves hand control and grip strength during weldingEnsures comfort during long working periodsUsing unsuitable gloves can lead to serious occupational accidents and loss of workforce.Things You Need to Know When Choosing Welding Gloves1. Suitability for the Type of Welding PerformedThe welding method is a determining factor in glove selection:MIG/MAG Welding: Heat-resistant gloves with medium flexibilityTIG Welding: Thinner gloves offering high finger sensitivityElectrode (MMA) Welding: Thick gloves with high heat and spatter protectionSince each welding method involves different risks, a single type of glove is not suitable for every application.2. Heat and Flame ResistancyWelding gloves must be produced from materials that are resistant to high tempatures. Commonly preferred materials include:Heat-resistant leather (cowhide, goatskin, or sheepskin)Flame-resistant stitching threadsLong-cuff designsInsufficient heat protection can lead to a serious risk of burns.3. Balance Between Glove Thickness and FlexibilityThe thicker the glove, the higher the level of protection; however, flexibility decreases.Therefore:Thinner and more flexible gloves should be preferred for precision workThicker gloves should be used for heavy-duty and intensive welding applicationAchieving the right balance improves both safety and welding quality.4. Wrist and Forearm ProtectionDuring welding, splashes can harm not only the hands but also the wrists and forearms.Therefore:Gloves with long cuffsDesigns that fully cover the wristprovide extra protection and enhance occupational safety.5. Standards and CertificationsWelding gloves must comply with relevant occupational safety standards.Particularly;EN 388 (mechanical risks)EN 407 (heat and fire risks)products that meet the above-mentioned standards should be preferred.6. Comfort and Long-Term UseWelding operations often involve long working periods. Therefore:Inner linings that reduce sweatingErgonomic cutsNon-slip surfacesincrease operator comfort and work efficiency.Safe and Professional Welding Practices with Gedik WeldingGedik Welding supports a professional approach not only in consumables and machines but also in occupational safety and the proper use of equipment.

What is a Welding Arc? How It Forms and Its Effects on Welding Quality What is a Welding Arc?

What is a Welding Arc? How It Forms and Its Effects on Welding QualityWhat is a Welding Arc?A welding arc is a high-temperature, controlled electrical plasma discharge that occurs between the electrode of the welding machine and the base metal. This arc melts the metal surfaces and creates a weld pool, allowing the parts to be permanently joined.Arc welding methods form the foundation of the most widely used welding techniques in the industry.How Does a Welding Arc Form?The formation of a welding arc occurs in three main stages:The electrode comes into contact with the workpiece.When the contact is broken, the electric current becomes ionized.An arc is generated between the electrode and the metal.The temperature of this arc can reach approximately 6,000–8,000°C. The resulting high heat allows the base metal and filler metal to melt in a controlled manner.Functions of the Welding ArcThe welding arc is not just a source of heat. It also:Melts the base metalTransfers the filler metal into the weld poolDetermines the shape of the weld beadAffects weld penetration and strengthTherefore, having a stable and controlled arc is critically important for welding quality.Types of Welding ArcsThe characteristics of the arc vary depending on the welding method:Short ArcSuitable for thin materialsLess spatterControlled heat inputSpray ArcOperates at high currentProvides deep penetrationPreferred for thick sectionsPulsed ArcBalances heat inputLow spatterHigh weld qualityIn particular, in modern MIG/MAG and TIG welding machines, arc control is digitally optimized.Factors Affecting Welding Arc StabilityFor a welding arc to remain stable, the following factors are important:Correct current and voltage settingsProper selection of electrode or wireType and flow rate of shielding gasTorch angle and welding distanceArc control technology of the welding machineIncorrect settings can cause spatter, porosity, insufficient penetration, and weak weld formation.The Relationship Between Welding Arc and Welding QualityA stable welding arc results in:Smoother and more aesthetically pleasing weldsHigher mechanical strengthLess need for reworkLower consumption of consumablesThis provides advantages in production in terms of time, cost, and quality.Gedik Welding with Controlled and Powerful Arc PerformanceGedik Welding offers maximum performance in industrial welding applications through welding machines equipped with advanced arc control technologies, as well as high-quality welding wires and electrodes. Our products adapt to different arc characteristics, helping to achieve stable, reliable, and repeatable welding results.ConclusionThe welding arc is the heart of the welding process. Proper formation and control of the arc directly affect the strength, appearance, and performance of the weld. A welding arc created with the right equipment and correct parameters is the key to long-lasting and reliable joints.

Things You Should Know While Choosing Casting Electrodes

Things You Should Know While Choosing Casting ElectrodesStrong Welds with Low Risk of Cracks Using the Right ElectrodeWhy Is Electrode Selection Critical in Casting Welding?Casting materials are among the most difficult materials to weld due to their high carbon content, brittle structure, and heterogeneous microstructure. Incorrect electrode selection can lead to serious problems such as post-weld cracking, breakage, hardening, and loss of machinability.Therefore, choosing the right electrode for casting welding is a fundamental factor for welding success.1. Correctly Identify the Type of Casting MaterialBefore selecting an electrode, the type of casting material to be welded must be clearly identified:Gray cast ironDuctile (spheroidal graphite) ironMalleable (tempered) ironWhite cast ironSince each type of casting has different mechanical properties, using a single type of electrode is not appropriate.2. Prefer Nickel-Based ElectrodesNickel-based electrodes are the most common and reliable choice in casting welding.Pure nickel electrodes:High machinabilityLow risk of crackingIdeal for precise and repair weldsNickel-iron (Ni-Fe) electrodes:Higher mechanical strengthSuitable for parts subjected to heavy loadsThe correct alloy should be selected according to the purpose of the application.3. Consider Post-Weld Machinability RequirementsIf machining will be performed after welding, the electrode selection should be suitable for this purpose.Pure nickel electrodes → high machinabilityHigh-iron electrodes → harder structureThis criterion must be taken into account for repair and maintenance applications that require machinability.4. Electrode Selection to Minimize Cracking RiskThe greatest risk in casting materials is cracks that form during cooling. Therefore, electrodes should be chosen that:Have low hydrogen contentFeature designs that control heat inputUse alloys that provide elastic and tough weld metal5. Welding Method and Application ConditionsIn casting welding, the following are generally applied:Electrode (MMA) weldingLow amperageShort welds (step welding)The electrode must be suitable for these working conditions.6. Consider Preheating and Cooling ConditionsElectrode selection should also take into account the preheating method to be applied:Preheated weldingCold welding (without preheating, controlled)Some electrodes are more suitable for use with low preheating.7. Standards and Application SafetyThe selected casting electrode should:Comply with EN, ISO, or AWS standardsBe suitable for the welding positionHave clear application instructionsThese criteria are of great importance for industrial safety and quality.Reliable Solutions in Casting Welding with Gedik WeldingGedik Welding offers nickel-based casting electrodes developed for casting repair and manufacturing applications, providing welds that are durable, machinable, and have a low risk of cracking.
