He was burly, a bit heavy around the waist, wore thick glasses, and smoked cheap cigars in a cigar holder with a small mouthpiece, which gave his face a peculiar pinched look when he sucked on it.

他长得高大结实，腰部粗壮，戴副厚厚的眼镜，用一个雪茄烟嘴抽廉价雪茄，烟嘴口很小，他每抽一口，脸上都会有一种被夹痛的的独特表情。

Flat Welding : choice of welding technology, electrode diameter, welding current, welding speed, the length of arc welding, weld process verification; Welding : welding inspection clearance groove, assembly space whether it meets the requirements, positioning it firmly welding, weld around is not oil, rust; Electrode temperature and baking time should be required, the rod removed from the oven. tempreture-constant drum on the electrode, then used as admission; Latin America : welding supply welding thickness, welding levels and electrode type and diameter, skilled welders and other factors, and to select appropriate welding current; fillet weld arc : fluctuations in the point arc weld end, they are advised more than 10 mm, is not hard arc, sparking arc weld zone from the electrode should be started immediately. Component integration and maintaining so-rod pieces have 2-4 mm gap arc.

1.1.2.1平焊：选择合适的焊接工艺，焊条直径，焊接电流，焊接速度，焊接电弧长度等，通过焊接工艺验证；清理焊口：焊前检查坡口、组装间隙是否符合要求，定位焊是否牢固，焊缝周围不得有油污、锈物；烘焙焊条应符合规定温度与时间，从烘箱中取出的焊条，放在焊条保温桶内，随用随取；焊拉电源：根据焊件厚度、焊接层次、焊条型号、直径、焊工熟练程度等因素，选择适宜的焊接电流；引弧：角焊缝起落弧点应在焊缝端部，宜大于10㎜，不应随便打弧，打火引弧后应立即将焊条从焊缝区拉开，使焊条块结合与构件间保持2～4㎜间隙产生电弧。
