  轻轻钢结构主要由钢梁、钢柱、钢桁架和其他组件,这通常是通过焊接连接,螺栓或铆钉。焊接前需要严格的处理,焊接过程中有很多困难。
  Light steel structures are mainly composed of steel beams, steel columns, steel trusses and other components, which are usually connected by welding, bolts or rivets. Strict treatment is required before welding, and there are many difficulties in the welding process.
  1. 焊道应将基材与坡口内垫板的连接处密封,然后逐层焊接,直至坡口填满。每道焊缝焊接后,应清除焊渣和飞溅。
  1. The joint between the base material and the base plate in the groove shall be sealed in the weld bead, and then welded layer by layer until the groove is filled. After each weld is welded, the welding slag and spatter shall be removed.
  2、轻钢结构焊接的一般顺序是:焊前检查、预热除锈、焊垫和电弧板、焊接、检查。
  2. The general welding sequence of light steel structure is: pre welding inspection, preheating and derusting, welding pad and arc plate, welding and inspection.
  3.焊接前应检查坡口角度、钝边、间隙及口数是否正确。沟槽内、两侧锈斑、油渍、氧化铁皮等应清洗干净。
  3. Before welding, check whether groove angle, blunt edge, clearance and number of openings are correct. Rust spots, oil stains, oxide scales, etc. inside and on both sides of the trench shall be cleaned.
  4. 预热:焊接前,用气焊或专用格栅枪将基材在坡口及其两侧100mm范围内均匀加热,并用表面温度计测量温度,防止温度不符合要求或局部表面氧化、预热温度。

  4. Preheating: before welding, use gas welding or special grid gun to evenly heat the base material within 100mm of groove and both sides, and use surface thermometer to measure the temperature to prevent the temperature from not meeting the requirements or local surface oxidation and preheating temperature.
  5、重新检查预热温度,如温度不够应重新加热以满足要求。
  5. Recheck the preheating temperature. If the temperature is not enough, reheat it to meet the requirements.
  钢结构在焊接过程中如遇雨、下雪应停止焊接,且焊接构件周围及以上应有防风罩、雨棚,当环境温度低于零时,应按规定采取预热和后加热措施。
  In case of rain and snow during the welding process of steel structure, the welding shall be stopped, and wind shield and canopy shall be set around and above the welding components. When the ambient temperature is lower than zero, preheating and post heating measures shall be taken as required.
