Abstract
The invention discloses a plasma and TIG double-gun welding method applicable to nickel and a nickel alloy and aims at eliminating defects of gas holes, undercuts and incomplete fusion produced during welding of the nickel and the nickel alloy and improving the quality of nickel and nickel alloy welding connectors. Relative to the automatic walking direction of a nickel and nickel alloy cut deal or pipe (3), a plasma welding gun (1) and a TIG welding gun (2) are fixed, the plasma welding gun (1) is in front of the TIG welding gun (2), and the distance (L) between a tungsten electrode of the plasma welding gun (1) and a tungsten electrode of the TIG welding gun (2) is larger than 60 mm.
Description
Technical field
The present invention relates to the solder technology of nickel and nickel alloy.
Background technology
Nickel and nickel alloy fusing point height, mechanical property and hot and cold pressure good processability, excellent corrosion resistance, are heat-resisting dense
The preferred materials of alkali soluble corrosion, are widely used in steel and iron industry, space flight and aviation, mechanical industry, petrochemical industry and building industry.Pure
The thermal conductivity of nickel is low, poor fluidity, and solid liquid phase temperature range is little, is also easy to produce pore, undercut, incomplete fusion etc. and lacks in welding process
Fall into.Nickel and nickel alloy cut deal or tube welding select plasma welding method, disposable through welding, one side welding with back formation, weldering
Connect efficiency high, weldquality good.But plasma column is thin, appearance of weld is sensitive to electric arc centering, and plasma gun must be tight
Lattice ground be aligned weld seam just can obtain higher joint quality.
Content of the invention
The purpose of the present invention be eliminate nickel and nickel alloy welding when produce pore, undercut, the defect of incomplete fusion, improve nickel and
The quality of nickel alloy welding point.
The present invention applies to plasma and the TIG rush-harvesting and rush-planting welding method of nickel and nickel alloy, and in Fig. 1, shown in arrow, direction is
Nickel and nickel alloy cut deal or pipe 3 automatically walk direction, with respect to nickel and nickel alloy cut deal or pipe 3 automatically walk direction, etc.
Ion welding gun 1 is maintained static with TIG welding gun 2, plasma gun 1 front, TIG welding gun 2 subsequently, the tungsten electrode of plasma gun 1 with
The tungsten electrode of TIG welding gun 2 apart from L, be more than 60mm apart from L.
The beneficial effect that the present invention brings：Decrease the front groove fit-up gap to nickel and nickel alloy cut deal or pipe of welding
The requirement of precision, improves the appearance of weld of plasma list rifle welding, improves speed of welding and the performance of welding point,
Compared with multi-pass welding, can save the time, production efficiency is greatly improved again.
Brief description
Fig. 1 is the schematic diagram of plasma and TIG rush-harvesting and rush-planting welding, reference and entitled：Plasma gun 1, TIG welding gun
2, nickel and nickel alloy cut deal or pipe 3.
Specific embodiment
As shown in figure 1, the present invention applies to plasma and the TIG rush-harvesting and rush-planting welding method of nickel and nickel alloy, arrow in Fig. 1
Shown direction is nickel and nickel alloy cut deal or pipe 3 automatically walk direction, with respect to nickel and nickel alloy cut deal or the automatic row of pipe 3
Walk direction, plasma gun 1 is maintained static with TIG welding gun 2, plasma gun 1 front, TIG welding gun 2 subsequently, plasma gun 1
The tungsten electrode of tungsten electrode and TIG welding gun 2 apart from L, be more than 60mm apart from L.
As shown in figure 1, being more than 60mm apart from L, less than 150mm.
Embodiment：When nickel and nickel alloy cut deal or pipe automatic welding, using plasma and TIG rush-harvesting and rush-planting welding method, press
According to welding direction, before plasma gun 1 is fixed on, subsequently, between two rifles, distance is adjustable for TIG welding gun 2, corresponds to nickel and nickel alloy ions
The tungsten electrode of welding gun 1 selects 60 150mm with the tungsten electrode of TIG welding gun 2 apart from L, after the welding waste heat of plasma postwelding can be
Energy is reduced in face TIG welding cap face, and molten bath high-temperature residence time is long, eliminates nickel and nickel alloy is produced due to molten bath poor fluidity
Undercut, the weld defect such as pore, increase speed of welding, improve production efficiency.When two rifle distances are less than 60mm, plasma
Welding and TIG weld heat input are big, and high temperature easily causes welding gun to ftracture；When distance is more than 150mm, plasma postwelding waste heat subtracts
Little, TIG electric current one timing, face of weld remelting effect is deteriorated, and only increases TIG electric current, just can be conducive to pore in weld seam
Effusion, improves face of weld undercut phenomenon.Two rifles weld simultaneously, the advantage making full use of Plasma Welding and TIG weld, weldering
The seam back side obtains stable formation, and the defect of face of weld substantially eliminates, and shapes attractive in appearance, and quality of weld joint is high.Therefore, plasma
Weld nickel and nickel alloy cut deal or pipe with TIG rush-harvesting and rush-planting, welding efficiency is high, lumber recovery is high, is a kind of preferable welding method.
