Abstract
A flux for the tungsten-electrode argon arc welding of stainless steel contains SiO2 (50-80 wt.%), TiO2 (2-30 wt.%), Al2O3 (2-15 wt.%), Cr2O3 (5-25 wt.%), CaO (1-10 wt.%), MgO (1-10 wt.%) and MnO (1-10 wt.%). Its advantages are deep depth of welded seam (increased by 2-3 times), high welding efficiency increased by more than once, and low cost.
Description
The invention belongs to the solder technology of stainless steel material, relate generally to a kind of flux for argon tungsten arc welding of stainless steel.
Existing argon tungsten arc welding of stainless steel belongs to the inert gas-shielded arc welding welding method.Because its protection effect is fine, in argon tungsten-arc welding, do not use solder flux that the metal in the welding pool is further protected basically.When yet existing argon tungsten arc welding of stainless steel welding method is welded, following shortcoming is arranged: 1, the welding bead fusion penetration of single face welding and double face shaping limited (about 3mm), obtainable maximum weld penetration also very limited (about about 4mm), this just causes this welding method welding efficiency low, is usually used in the welding less than the material of 6mm of the single face welding and double face shaping bottoming welding of root pass and thickness.When being used for the welding of thicker material, roll up owing to be used for filling the welding bead quantity of groove, welding cost sharply increases, and welding efficiency is lower, makes that the practicality of this welding method is poorer.2, welding deformation is bigger, owing to adopt the groove welding, welding deformation is difficult to avoid, and welding deformation amount becomes big with the increase of welding bead quantity.3, the fluctuation meeting of the content of the minimal residue element of PPm level makes a difference to the argon tungsten arc welding of stainless steel weld penetration, makes the poor stability of welding procedure especially to be unfavorable for the welding of single face welding and double face shaping.
Purpose of the present invention promptly is to propose a kind of flux for argon tungsten arc welding of stainless steel, existing the problems referred to above when welding by using this solder flux to solve existing argon tungsten arc welding of stainless steel.
Flux for argon tungsten arc welding of stainless steel proposed by the invention is made of multiple oxide mixing; The component of solder flux and consumption (percentage by weight) are: SiO
250～80 TiO
22～30 AL
2O
32～15 Cr
2O
35～25 CaO, 1～10 MgO, 1～10MnO 1～10.
The granularity of solder flux solvent of the present invention takes by weighing by mass percentage greater than 300 orders, with claim component place milling apparatus fully to grind to make it absorption mutually and homogenising, the drying cooling is mixed and made into an amount of acetone or MEK.The coating that solder flux of the present invention forms can make the electric arc of argon tungsten-arc welding that strong the contraction taken place, and makes weld penetration increase by 2～3 times, and the structure property of butt welded seam metal does not have tangible harmful effect simultaneously.After the solder flux that adopts the present invention to propose is brushed coating, when adopting conventional argon arc welding equipment to carry out the butt welding of thick stainless steel materials of 3～8mm or pipe fitting, can adopt the straight flange groove, need not add welding wire, promptly finish the single face welding and double face shaping welding of banjo fixing butt jointing together, and welding deformation minimum (angular deformation of sheet material butt joint is almost nil under the free state), therefore welding efficiency improves more than at least one times, welding cost reduces significantly, Type of Welding is greatly simplified, and is about 1/3 of the conventional argon arc welding adopting double V-groove and add welding wire weld interval.Adopt solder flux of the present invention, can greatly reduce welding deformation simultaneously, eliminate the adverse effect that the content of elements fluctuation is produced.
