Steel Square Tube - Let's Know How ERW Tube Get Prepared
Steel tube starts out as plane steel strip that has been split to the accurate width for the ending tube size. It is then passed throughout a series of rolls that form it into an encircling tube. Behind the steel has been shaped it passes throughout a welding package. The weld box for ERW tube uses electrical resistance of the steel tube to generate heat. This heat is what link the 2 steel ends jointly. Using this technique will make a strong weld that is just as sturdy as or stronger than the innovative steel.
