What is welding electrodes

Welding Electrodes.... Welding rods, which are also known as electrodes, are essentially the welding material that gets melted and infused in processes like stick welding. To use a welding rod, it gets connected to your welding machine which then creates an electric arc between the base metal. Because this electric arc is very hot, it quickly melts the metal so that it can be fused for the welding process. वेल्डिंग रॉड, जिन्हें इलेक्ट्रोड के रूप में भी जाना जाता है, अनिवार्य रूप से वेल्डिंग सामग्री है जो स्टिक वेल्डिंग जैसी प्रक्रियाओं में पिघल जाती है और संक्रमित हो जाती है। वेल्डिंग रॉड का उपयोग करने के लिए, यह आपकी वेल्डिंग मशीन से जुड़ जाता है जो तब बेस मेटल के बीच एक इलेक्ट्रिक आर्क बनाता है। चूंकि यह विद्युत चाप बहुत गर्म होता है, यह धातु को जल्दी से पिघला देता है ताकि इसे वेल्डिंग प्रक्रिया के लिए फ्यूज किया जा सके।

Welding electrode for Mild Steel and High chromium alloy joint

5. Two Dissimilar Hard material welding Nickelarc 141 Typical applications Nickelarc 141 would involve the chemical industry, soda, fabrication, fatty acid fabrication, vinyl chloride production, sodium metal silicate production and within the paper industry. Nickelarc 141 should be considered where high resistance to corrosion and high temperature is required. Nickelarc 141 is a high nickel content flux-coated electrode designed for welding wrought and cast forms of commercially pure nickel to themselves or to steel. This electrode is commonly used for dissimilar welding applications involving nickel base alloys 200 or 201 to iron base and nickel base alloys. Nickelarc 141 is excellent for overlaying on steel and for welding the clad side of nickel clad steel. NOTES ON USAGE Its weldability is as same as austenitic stainless steels. Keep the interlayer temperature under 100ºC and cool it as fast as possible. Keep the welding current as low as possible. Dry the electrodes at 150 ~

Hard Facing electrode

4. Hard Facing welding electrode Welding Alloys offer a range of covered electrodes for hard facing. Our hard facing electrodes are the ideal manual welding solution for welding parts subject to wear. Our range of coated electrodes are suitable for repair, rebuilding and hard facing of parts such as cutting tools, forging tools, cones, mantles, earth moving equipment and many more. For joining and building up of low and medium carbon steels. Ideal for joining dissimilar sections, restrained joints and oil soaked parts. Can also be used as a cushioning alloy under hard facing deposits. Finds applications in pressure vessels, pipes, flanges, vehicle chassis, cross members, gun plates, heavy machinery parts, steel castings, etc. Hard facing electrode N6006- We generally using hard facing Chromocarb N6006 L&T Welding Electrode. these electrode highly resist wearing area like as Coal mill, Coal pipe, Classifier, Roller , Vehicle chassis etc. To resist wear from parts rolling or slid

Welding joint between Steel to Mild Steel

2. Welding between Steel to Mild Steel We here talking about different metal welding work (Dissimilar metal welding joint). In thermal plant some areas application where we must need to weld two dissimilar metal. We all know that Mild steel less costly rather than Stainless steel but in some areas where we need hard and long time rubbing structure we required than we made from stainless steel and for reducing cost of structure we use both material sheet to together Mild Steel sheet and Stainless steel. For jointing Mild Steel with Stainless steel we use 3 09 Welding Rod Application- We using stainless steel with mild steel structure in coal feeder areas , coal pipe on band, Steel valve welding flange with mild steel etc. Electrode 309 ESAB ESAB 309 is specially designed for the welding of AISI 309 type steels, straight chrome steels dissimilar steels for e.g. welding of mild steels to stainless steels, low alloy steel to stainless steels etc. It is also used for surfaci

Chose welding electrodes

Different types of welding electrodes Normal welding electrodes- Welding joint between Steel to Mild Steel Hard Facing electrode Welding electrode for Mild Steel and High chromium alloy joint For Simply for welding purpose we generally use 7018 and 6013. These above two electrodes use for general purpose , This 7018 and 6013 electrodes is very must useful in rusty - dusty areas. Applicable for - Vehicles bodies joint Ship Structure welding works Mechanical Structure works Beams and structure works Welding Electrode 7018. 7018 = 70 and 1 and 8 Frist two digit show Tensile strength of electrode material 70= 70000 Pounds per square Inch Tensile Strength Third Digit show the welding position Mainly three position of welding if 1= Stands for all positions 2= For flat and horizontal positions 4= Stands for overhead, vertical, horizontal, and flat electrode positions. Fourth Digit show the taking current during welding The last digit implies the coating that has been used and consequ
