Welding flanges:Non-destructive testing of butt
06-04
Thin butt-welded flanges are often single-sided welding. In order to achieve penetration, the butt-welded flange should be left with a space of 1.4~1.6mm.  Using thin welding wire (0.8~1.2mm in diameter) for short-circuit transfer welding, the welding current is 120~130A, and the arc voltage is 18~1
Pipe processing ---have six methods of bending it
06-02
There are mainly the following six methods of pipe bending in the pipe bending factory   Stamping method: Use a tapered core on the punch to expand the pipe end to the required size and shape.  Rolling wheel method: Put a core in the tube, and push the outer circumference with a roller for round edg
Submerged arc welded pipes VS high frequency welding
05-31
