Description
Technical field
The present invention relates to a kind of welding production technology and device of steel pipe, the novel welding production technology of particularly a kind of steel pipe of double T IG electric arc can be realized the high-speed welding of thin-wall steel tube and the backing welding of thick walled steel tube with this welding method.
Background technology
Solder technology is the key technology of present steel pipe's production, and it has determined the quality and the efficient of steel pipe's production, and the restriction of various different welding technique speeds of welding becomes a main difficult problem that improves output of steel tube.(steel pipe of wall thickness≤3mm), DC TIG welding is one of its main welding production technology for thin-walled.As for industrial stainless steel tube, both required the shaping of steel pipe seam complete penetration and surfaces externally and internally attractive in appearance, require weld seam to have higher mechanical property again.Therefore, speed of welding becomes the bottleneck that stainless steel tube welding output improves.Under the condition of not considering the tungsten electrode scaling loss, adopt big electric current welding, welding is produced for wall thickness 1.5mm stainless steel tube, and speed of welding is only up to 1.8m/min, and for the thick stainless steel tube of 1.0mm, its welding speed of production reaches as high as 2.5m/min.If further improve speed of welding again, then can cause shaping surface defectives such as face of weld undercut, pit, hump welding bead and influence weld properties, thereby cause tube quality not up to standard in order to improve stainless steel tube output.Therefore, guaranteeing that appearance of weld and mechanical property reach under the condition of standard-required, improving speed of welding and become the difficult problem that thin-wall steel tube manufacturing enterprise raising output is faced jointly.
Although high-frequency resistance welding (HFRW) can reach very high speed of welding, because the overlap of inside pipe wall is difficult to remove, can not satisfy the requirement that the butt welded seam inner surface is shaped, limited its application in industrial steel pipe's production that the inside pipe wall appearance of weld is had certain requirements.Welding technique as a kind of high-energy-density, plasma arc welding (PAW) also can realize the welding of fair speed, but after speed surpassed 2～3m/min, its appearance of weld is the same with the TIG weldering also can be occurred such as forming defectses such as undercut, pit, humps.In addition, the relative TIG weldering of high-frequency resistance welding (HFRW) with plasma arc welding (PAW), what the cost of its welding equipment will be high is many.
For ferrous materials such as stainless steels, because the viscosity of liquid metal is big, under high speed TIG welding condition, under the repulsive interaction and motional inertia effect of arc force, molten pool metal is mainly piled up to the rear, molten bath.Because speed of welding is fast, the molten bath cooling velocity is also fast, the liquid metal that is stacked into the rear, the molten bath just solidification forming that also do not have enough time to reflux when filling the molten bath that subsides, thereby cause shaping surface defectives such as undercut, pit and hump welding bead, the weld seam one side shaping surface that has these defectives to exist is not up to standard, has seriously reduced the mechanical property of weld seam on the other hand yet.According to the reason that the appearance of weld defective forms, adopt additional heating source to prolong the time that liquid metal exists, so that can being refluxed, it fills the depression in molten bath, form flat, the continuous weld seam of surfacing.
Summary of the invention
The object of the invention provides a kind of thin-wall steel tube high-speed welding production technology and device, this technology not only can realize the high speed of thin-wall steel tube, efficient welding production, can also realize deliver a child high speed backing welding in producing of thick walled steel tube multilayer welding, solve the technical barrier that the thin-wall steel tube welding yields poorly.
