Construction steel butt welding or welding good?
First of all, consider the construction of steel products to be welded quantity and strength requirements.The butt welding belongs to pressure welding and is suitable for mass production in batches.Electric welding is melting welding, its operation is flexible, suitable for field welding, and the two welding methods are different in use, so they can not be replaced by each other.From the performance of the joint, the welded joint is well welded, so the quality of welding is higher than that of the welding.
If you have to choose the resistance butt welding electrode arc welding steel bar, then resistance butt welding.However, the power consumption of resistance butt welding is great, and the rate of welding finished products is lower than that of electroslag welding. The efficiency of electrode welding is low.Vertical electroslag welding of steel bars is better. Welding machine load rate is not less than 60%,However, welding machine at least 500A, the maximum can be welded 25 mm diameter steel bar,630A can weld steel bars of 32 millimeters in diameter.Welding efficiency of welding rod is low.
