Abstract： This article mainly introduces the breakthrough of narrow gap MAG welding system in solving the problem of groove welding of thick walled pipe fittings， It can control the groove width within 12mm， save welding materials， and control welding quality. At the same time， it can optimize the grain structure of the weld seam， improve the strength of the weld metal make the seam beautiful， and improve the quality of the quality of the weld seam.

Keywords： narrow gap; MAG automatic welding process; welding quality

1 序言

近幾年，隨著國內(nèi)液壓支架生產(chǎn)規(guī)模的不斷擴(kuò)大，立柱作為液壓支架主要組成部件，其焊接工藝及生產(chǎn)設(shè)備也亟需優(yōu)化和提升。（剩余5521字）
