Abstract
The invention discloses a welding process of a stainless steel control box. The welding process is characterized in that the wall thickness of the control box is 7 millimeters; a V-shaped or U-shaped or X-shaped groove is formed at a welding position; for a welding piece, a filling welding wire is subjected to oil removal and descaling; for welding parameters, welding current is 240 to 260A, arc length is 0.5 to 3 millimeters, arc voltage is 8 to 10V, welding speed is 5 to 10 millimeters/second, and protection airflow is carbon dioxide gas; direct current is adopted for welding, and an electrode serves as an arc carrier and also serves as a welding line filling material; the electrode comprises an alloy or non-alloy metal core wire and a welding rod cover, and the cover is used for protecting a welding line from being damaged due to air and stabilizing arc, gives rise to forming a slag layer, and protects the welding line to be formed; and an electric welding rod is a titanium welding rod or an alkaline welding rod. The welding process is simple to operate and has a good welding effect on a stainless steel plate, the welding line is flat and smooth with good airtightness, and a component in the control box is protected from outside pollution, and is ensured to be reliable in performance.
Description
Technical field
The present invention relates to slab housing welding technology field, particularly a kind of welding procedure of stainless steel control box.
Background technology
At present, the slab housing is generally the welding of the sheet material more than 5 millimeters, the bad problem of weld joint close sealing property often occurs, and the difference of parameter control causes weld seam width to differ greatly during simultaneously owing to operation, and aesthetic property is poor.
Summary of the invention
The objective of the invention is in order to improve welding quality, the spy provides a kind of welding procedure of stainless steel control box.
The invention provides a kind of welding procedure of stainless steel control box, it is characterized in that: the welding procedure of described stainless steel control box is manual welding, and the control box wall thickness is 7mm, and weld is opened V, U or double V groove, butt-welding fitting, filler wire carries out oil removing and descale;
Welding parameter: welding current 240 ~ 260A, arc length is 0.5 to 3mm, arc voltage 8 ~ 10V, speed of welding 5 ~ 10mm/s, shielding gas flow are carbon dioxide, gas flow 20 ~ 25L/min, the distance 15 ~ 25mm between tip and workpiece, nozzle diameter 2 ~ 6mm; Direct current is adopted in welding, and electrode is both as arc vector, simultaneously also as the weld seam packing material; Electrode is comprised of alloy or non-alloying metal core silk and electrode coating, and this layer coating protection weld seam is not subjected to the infringement of air, Simultaneous Stabilization electric arc, and it also causes the formation of slag blanket, the protection weld seam makes its moulding; Welding rod is rutile type electrode or basic electrode.
Advantage of the present invention:
The welding procedure of stainless steel control box of the present invention, simple to operate, good to the welding effect of stainless steel materials, smooth welded seam is smooth, and good airproof performance guarantees that components and parts are not subjected to outside contamination, dependable performance in the control box.
