Ubushinwa bukora LSAW na SSAW Umuyoboro Welded
Ubushinwa Umuyoboro wibyuma hamwe nicyuma gisudira
vuba aha twahuye nubushakashatsi bwumuyoboro usudira mugihe cyiperereza ridafite kashe.
Hariho inzira ebyiri zo gusudira. Imwe ni Spirally Submerged Arc Welding (umuyoboro wa SSAW), indi ni ndende ya marike yo gusudira arc gusudira (umuyoboro wa LSAW)
Kuri LSAW, hari umuyoboro umwe wo gusudira hamwe numuyoboro wikubye kabiri. urashobora kugenzura amashusho

Gusaba
Irakoreshwa Cyane kubice byingufu nigitutu, no mubikorwa rusange ibyuka, amazi, gaze numuyoboro wikirere.
