6. a two-tube welding method that adopts station boiler column pipe tray automatic welding machinery device as claimed in claim 1, its objective is and between two column pipes (7), weld row's tray (8), and it is characterized in that, step is:
The first step, many column pipes (7) bin (1) before weldering that needs are welded are arranged in a row;
Second step, by poking device (3) by bin (1) before welding arrange the most front column pipe (7) and below a column pipe (7) dial and drop down onto before weldering on raceway (2);
The 3rd step, by air clamper separately, clamped respectively the rear end that is positioned at two column pipes (7) on raceway (2) before weldering, by servo motor device, by pinion and rack and air clamper, drive column pipe (7) to send the front end of two column pipes (7) to heating system by required step pitch simultaneously, by heating system, adopt beat-type mode of heating that upper each part to be welded of column pipe (7) is heated to temperature required successively;
The 4th step, by servo motor device, continued column pipe (7) heating part to send to welding main frame (4), two column pipes (7) location that will be positioned at respectively homonymy by two two-tube positioning clamping devices (4-6) of welding main frame (4) clamps;
The 5th step, charging finger (4-11) rise the tray of being sent here by two-tube feed bin (8) are delivered between two column pipes (7);
The top welding gun (4-8) of the 6th step, every assembly welding rifle is aimed at respectively and is positioned at the weld seam that is positioned at homonymy between tray (8) and column pipe (7), along this weld seam, by servo-electric cross straight line balladeur train (4-10), carries out cornerite welding;
The 7th step, charging finger (4-11) decline, the bottom welding gun (4-9) of every assembly welding rifle is aimed at respectively and is positioned at the weld seam that is positioned at homonymy between tray (8) and column pipe (7), along this weld seam, by servo-electric cross straight line balladeur train (4-10), carries out cornerite welding;
After the 8th step, a tray (8) have welded, servo motor device is sent two column pipes (7) to a step pitch, return to the 6th step and repeat, until complete current column pipe (7), need after the welding of welding tray (8), enter the 9th step with all;
Two column pipes (7) after the 9th step, welding drop down onto after postwelding bin (6) via postwelding raceway (5), return to second step and continue to carry out, until all column pipes (7) on bin (1) before welding are all welded complete.
