Butt Weld and docking and corner combinations Weld, in Weld ends located arc plate and extraction plate in igniting board then leads to the welding seam, joint halfway shall weld joints in front of 2.0 mm Department Firing arc, welding pieces after preheating rod will return to weld the origin, pool filled to the required thickness, before forward welding; Welding speed : Isokinetic welding requirements to ensure weld thickness, width uniform, which masks to look for hot metal and slag bath equidistance (2-3 mm)%; Arc welding rod length : different models and determined that the general requirements of arc length is stable, acid electrode generally 3-4 mm, 2-3 mm normally alkaline electrode%; Welding perspective : According to determine the thickness of two pieces of welding, welding angle has two aspects : First, the angle between the direction of the rod and welding of 60-75 ; The second is the angle between two electrodes and welding around, the same thickness as welding, welding and welding pieces incident angle of 45 ; When the thickness ranging from welding, welding electrode and thick and thin pieces of welding electrode side angle greater than the angle between the side pieces; Arc : admission to the end of each weld should be filled crater, in the direction opposite to the direction of the back-arc welding, arc welding unchanged inside pit in 1974, to prevent the crater bite of meat.

对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方15～20㎜处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（2～3㎜）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为3～4㎜，碱性焊条一般为2～3㎜为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为60～75 ；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为45 ；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。
