在钢结构搭建的焊接过程中，需要注意以下细节：焊接前应检查焊缝的坡囗形式、尺寸、间隙等是否符合要求，并清除坡囗两侧的锈迹、油污等杂质。焊接时应根据钢材的材质、厚度、焊接位置等选择合适的焊接工艺和焊接参数，如焊接电流、电弧电压、焊接速度等。

During the welding process of steel structure construction, attention should be paid to the following details: before welding, the groove form, size, gap, etc. of the weld seam should be checked to ensure that they meet the requirements, and rust, oil stains, and other impurities on both sides of the groove should be removed. During welding, appropriate welding processes and parameters should be selected based on the material, thickness, and welding position of the steel, such as welding current, arc voltage, welding speed, etc.

焊接时应保证焊条或焊丝的干燥，并按照规定的要求进行烘干、保温等处理。焊接时应控制好焊接温度，避免过热或过冷，保持适当的温度范围。焊接时应采用正确的焊接顺序，避免出现未焊透、未熔合等缺陷。

During welding, it is necessary to ensure that the welding rod or wire is dry and undergo drying, insulation, and other treatments according to the specified requirements. During welding, the welding temperature should be controlled to avoid overheating or overcooling and maintain an appropriate temperature range. The correct welding sequence should be used during welding to avoid defects such as incomplete penetration and fusion.

焊接时应随时检查焊缝的质量，及时发现和处理焊接缺陷，如气孔、夹渣、咬边等。焊接后应进行后处理，包括清除焊渣、飞溅等杂质，并进行焊缝的外观检查和无损检测。焊接时应采取安全措施，如穿戴防护服、手套、鞋等个人防护用品，避免出现烫伤、触电等安全事故。

During welding, the quality of the weld seam should be checked at all times, and welding defects such as porosity, slag inclusion, and undercutting should be detected and dealt with in a timely manner. After welding, post-treatment should be carried out, including removing impurities such as welding slag and spatter, and conducting visual inspection and non-destructive testing of the weld seam. Safety measures should be taken during welding, such as wearing personal protective equipment such as protective clothing, gloves, shoes, etc., to avoid safety accidents such as burns and electric shock.
