Without the Plate Flat Butt Welding Machine, joining any two pieces of steel plate involves below steps:
1) First carry out SAW welding on one side of the 2 pieces of steel plate;
2) 180° overturning the half-finished joint plate: This is time consuming step, embedded with potential safety risk, involving 2 operators working together;
3) Implement SAW welding on the opposing sides of the 2 pieces of steel plate;
4) Implement carbon arc gouging on finished joint steel plate;
Now, with powerful and efficient work of Plate Flat Butt Welding Machine,
1) One Time Going Through: The 2 pieces of steel plate can be beveled and joint with its passing through the Flat Butt Welder equipment, without the necessity of 180° flipping;
2) Only one side of SAW welding is necessary;
3) Only 1 operator is needed to complete the entire operation;
4) Cycle time is only 50% of original,
Delivering consistent and controllable joint seam quality from the Steel Plate Butt Joint Welding Machine;
