In the process of using straight seam automatic welding machine, according to different products, different matching products need to be configured.

1、對于2000mm以上的長焊縫工件的焊接，由于設備的誤差或者工件本身誤差，容易造成焊縫成型不好或者焊縫偏移，所以需要配置跟蹤系統(tǒng)或者擺動系統(tǒng)，可以克服由于焊縫彎曲而造成的咬邊或未焊透等缺陷，才能真 正實現(xiàn)自動焊接，達到提供效率和焊接質量的效果。右圖即為配套擺動器的直縫自動焊機。

1. For the welding of long seam workpieces over 2000mm, due to the error of the equipment or the workpiece itself, it is easy to cause poor weld forming or weld offset, so it is necessary to configure the tracking system or swing system, which can overcome the defects such as undercut or incomplete penetration caused by the bending of the weld, so as to truly realize automatic welding, To achieve the effect of providing efficiency and welding quality. The picture on the right shows the straight seam automatic welding machine with swinging device.

2、對于2mm以上厚度鋼板的筒體焊接，由于焊縫的間隙比較大，采用工件的母材自身熔化不能填平焊縫，形成焊接缺陷，這時需要加上自動填絲機構，在焊接過程中增加金屬的熔化量來填平焊縫，達到高質量的焊縫。

2. For the cylinder welding of steel plate with thickness more than 2mm, due to the large gap of the weld, the base metal of the workpiece can't fill the weld, forming welding defects. At this time, the automatic wire filling mechanism needs to be added to increase the amount of metal melting in the welding process to fill the weld, so as to achieve high quality weld.

3、直縫自動焊機的熱源選擇：直縫自動焊機的熱源主要有鎢極氬弧焊機、等離子焊機、CO2/MIG/MAG熔化極氣體保護焊機、埋弧焊機、激光焊機等。對于鋁、鎂及合金等，一般采用交流氬弧焊機或者MIG焊機焊接。對于不銹鋼可采用除CO2/MAG焊機以外的所有直流焊機。對于普通碳鋼可采用上述所有焊機。

3. Heat source selection of straight seam automatic welding machine: the heat source of straight seam automatic welding machine mainly includes tungsten argon arc welding machine, plasma welding machine, CO2 / MIG / MAG metal electrode gas protection welding machine, submerged arc welding machine, laser welding machine, etc. For aluminum, magnesium and alloy, AC argon arc welding machine or MIG welding machine is generally used. For stainless steel, all DC welding machines except CO2 / MAG welding machine can be used. All the above welding machines can be used for ordinary carbon steel.
