Abstract
The invention discloses a robot automatic welding method for stainless steel and copper dissimilar materials. The robot automatic welding method is characterized by including the following steps that step1, a copper connector is heated in an induced mode; step2, the copper connector and a stainless steel plate are clamped into a fixing clamp to be fixed; step3, a welding robot is started; step4, arc striking is performed along a marked correction position, position setting is performed according to a program, and then a whole welding seam is welded; step5, after welding is completed, the welding robot returns to the zero position. The robot automatic welding method has the advantages that the stainless steel and the copper are welded in a gas metal arc welding mode through the robot, the welding process is fully automatic, technology repeatability and welding efficiency are high, and welding quality is stable. The selection of various welding materials provides a big margin for selection of welding schemes.
Description
Technical field
The present invention relates to a kind of robot welding method of stainless steel and copper material foreign material, need to possess conduction and the parts of support structure in connecting for steam turbine generator structural member simultaneously, belong to steam turbine generator technical field.
Background technology
When stainless steel welds with copper material, because copper material and stainless steel material fusing point, thermal conductivity factor, linear expansion coefficient and mechanical property aspect exist larger difference, welding point is difficult to fusion, and has particular requirement to wlding and operation technique.In personnel's technical ability situation slightly devious, just easily cause the generation of weld crack.
Summary of the invention
The technical problem to be solved in the present invention is to provide the automation solutions that a kind of stainless steel welds with copper material.
In order to solve the problems of the technologies described above, technical scheme of the present invention there is provided robot automation's welding method of a kind of stainless steel and copper material foreign material, it is characterized in that, comprises the following steps:
Step 1, eddy-current heating copper sleeve, be preheated to more than 350 DEG C;
Fixing in step 2, clamping copper sleeve and corrosion resistant plate to stationary fixture;
Step 3, startup welding robot, wherein: welding robot and the source of welding current adopt all-digital interface to be connected, the source of welding current is for controlling the welding parameter of welding robot; The welding robot speed of travel is then controlled by routine data; Welding gun track on welding robot is then undertaken showing that school is determined by butt welding machine device people;
Step 4, edge show the starting the arc of position, school and follow procedure desired location completes the welding of whole piece weld seam, gage of wire Φ 1.2mm, wire feed rate 7.5m/min, speed of welding 13.5m/min, and welding current is according to wire feed rate, welding curve and fine setting parameter Auto-matching;
Step 5, welded after, welding robot return zero-bit.
Advantage of the present invention is realized by robot gas metal-arc welding mode with welding of copper material by stainless steel, and welding process is full-automatic, and process repeatability is high and welding efficiency is high, welding quality stable.The selection of multiple welding material provides very big nargin also to the selection of welding scheme.
Accompanying drawing explanation
Fig. 1 is stainless steel and copper material welding assembly schematic diagram;
Fig. 2 is robot welding system's schematic diagram;
Fig. 3 is the front view of stationary fixture in the present invention.
Detailed description of the invention
For making the present invention become apparent, hereby accompanying drawing is coordinated to be described in detail below with preferred embodiment.
The present embodiment is for being of a size of the TU2 copper sleeve 2 of 115mm × 73mm × 66mm and being of a size of the 0Cr18Ni9 corrosion resistant plate 1 of 77mm × 33mm × 5mm, and its welding method is:
As shown in Figure 1, be soldering stainless steel plate 1 and the trihedral angle weld seam of copper sleeve 2, first copper sleeve 1 Medium frequency induction be preheated to 450 DEG C.
Composition graphs 2 and Fig. 3, then load stationary fixture 6 by the copper sleeve 2 after preheating, and be encased inside by corrosion resistant plate 1, screws the workpiece relative position that briquetting 7 prevents welding process from causing because copper is different from the stainless steel hot coefficient of expansion and change.
Artificial unlatching welding robot 3 motor power, welding robot 3, after confirmation operation area safety signal is normal, starts to start each joint motor.By showing that school track six-axis linkage walks to the arcing point starting the arc to the welding gun on welding robot 3, by both fixed track continuation welding gun walkings, posture of welding torch conversion is carried out under track stage casing not blow-out state, continue subsequent weld welding, gage of wire Φ 1.2mm, wire feed rate 7.5m/min, speed of welding 13.5m/min, welding current is according to wire feed rate, welding curve and fine setting parameter Auto-matching.After having welded, robot returns zero-bit.In welding process, the welding gun speed of travel is controlled by the routine data of robot 3, and welding parameter is controlled by the source of welding current 4, and robot power supply starts or closedown is controlled by switch board 5.
Artificial closing machine people motor power, takes out postwelding joint from stationary fixture.
