For steel irrigation pipes, prices depend on diameter and weld quality, affecting overall job worth, estimated around $250. Labor costs also … Read more

In India, the arc welding cost per meter depends on the process. SMAW ranges from ₹200-500, MIG from ₹300-700, and TIG from ₹400-1000. Cost estimation factors include labor, materials, and project complexity. Reliable calculators help ensure accurate budgeting for welding projects. Additionally, the location and skill level of the welder can affect the overall cost. … Read more

Arc welding current adjustment is the process of setting the right amperage for effective welding. Amperage measures the strength of electrical current. This adjustment depends on metal thickness and welding type. For shielded metal arc welding (SMAW), a common amperage range is 70-80 A. Proper adjustments enhance weld quality and technique. Another technique includes adjusting … Read more

Plasma arc welding (PAW) is a welding process that uses a non-consumable electrode to create a focused electric arc. This arc generates high heat to melt and join metals. PAW runs on direct current with constant current settings. It is effective for welding metals up to 10 mm thick using a plasma welding torch, power … Read more
