焊接:焊接的完整命令检查,除锈、焊接预热板板,电弧焊接,检查
5.3.1坡口焊之前,坦率的出口型错缝两侧铁锈,氧化层干净。
5.3.2焊前预热。气焊或特别的枪两槽及范围矩阵100毫米加热,温度测量仪表面温度,防止温度不能达到或部分表面氧化、预热温度。
再次5.3.3预热,温度,例如温度,不能再接受这样的要求。
5.3.4接组装板板图号、清洁、地板表面要求的槽,金属板,金属板,一定得,号进入焊接必须坚决。
5.2.5焊缝必须一层密封层金属版结婚后逐渐满了焊接坡口焊后必须清渣焊接缺陷,应及时修理,磨损。
接口必须5.3.6连续焊接,焊接时不必被迫慢慢冷却,焊接前应按规定,供暖。
5.3.7雪停了,组件,焊接口周围的一定以上的雨伞风速风大米/ s的。环境温度是零下,预热后热措施,按照规定处理。
必须5.3.8碳钢焊接冷却焊接环境温度较低的低合金钢,必须结束后24小时焊接检查。

5.3.9焊机的空白页,检查人员。



Welding: welding complete order inspection, derusting, preheating plate welding, arc welding, inspection
Before the 5.3.1 groove welding, export the wrong open on both sides of the joint rust, oxide layer clean.
5.3.2 preheating before welding. Gas welding and special gun two troughs and matrix range 100 mm heating, surface temperature of the temperature measuring instrument to prevent temperature should not be reached or partial surface oxidation, preheating temperature.
Again 5.3.3 preheating, temperature, such as temperature, can not accept such requirements.
5.3.4 the assembly board drawing board, cleaning, floor surface requirements of the groove, metal plate, metal plate, must be, the number must be determined to enter the welding.
5.2.5 welding seam must be a layer of sealing layer metal plate after the marriage began to fill the groove welding must slag welding defects should be repaired in time, wear.
Interface must be 5.3.6 continuous welding, welding without being forced to slow cooling, welding should be in accordance with the provisions of heating.
5.3.7 snow stopped, the component, the welding interface around a certain amount of wind speed of the wind to the rice / s. The ambient temperature is below zero, and the heat treatment is to be treated in accordance with the regulations.
Must 5.3.8 carbon steel welding cooling welding environment of low alloy steel, must be over 24 hours after welding inspection.
5.3.9 welding machine blank page, check personnel.
