  輕輕鋼結(jié)構(gòu)主要由鋼梁、鋼柱、鋼桁架和其他組件,這通常是通過焊接連接,螺栓或鉚釘。焊接前需要嚴格的處理,焊接過程中有很多困難。
  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. 焊道應(yīng)將基材與坡口內(nèi)墊板的連接處密封,然后逐層焊接,直至坡口填滿。每道焊縫焊接后,應(yīng)清除焊渣和飛濺。
  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、輕鋼結(jié)構(gòu)焊接的一般順序是:焊前檢查、預(yù)熱除銹、焊墊和電弧板、焊接、檢查。
  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.焊接前應(yīng)檢查坡口角度、鈍邊、間隙及口數(shù)是否正確。溝槽內(nèi)、兩側(cè)銹斑、油漬、氧化鐵皮等應(yīng)清洗干凈。
  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. 預(yù)熱:焊接前,用氣焊或?qū)S酶駯艠寣⒒脑谄驴诩捌鋬蓚?cè)100mm范圍內(nèi)均勻加熱,并用表面溫度計測量溫度,防止溫度不符合要求或局部表面氧化、預(yù)熱溫度。

  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、重新檢查預(yù)熱溫度,如溫度不夠應(yīng)重新加熱以滿足要求。
  5. Recheck the preheating temperature. If the temperature is not enough, reheat it to meet the requirements.
  鋼結(jié)構(gòu)在焊接過程中如遇雨、下雪應(yīng)停止焊接,且焊接構(gòu)件周圍及以上應(yīng)有防風罩、雨棚,當環(huán)境溫度低于零時,應(yīng)按規(guī)定采取預(yù)熱和后加熱措施。
  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.
