CONFIGURATION SITUATION
GROOVE WELDING
Before welding, we have use big edge milling machine mill(taper process) the edge of the sheet. So the welding can go to the internal of the steel-sheet and make the structure have higher performance.
Orbital welding machines are used for welding, and manual strengthening and welding are performed at corners and reinforcements.
Our boom and arm are large-welded box structure and thick or multi-plates for high-stress areas
