I. Summary and features:
1. Summary:
1.1、THCD-9 is a walking welding equipment driven by gears and chains, with built-in high-performance permanent magnets. The welding gun clamping mechanism can exchange clamping gas shielded welding guns and argon arc welding guns, which are used for butt welding of pipelines, fillet welding of pipelines and flanges or elbows, etc. The clamping argon arc welding guns can be used as argon arc welding machines.
1.2、The whole machine is compact, light and stable in structure; The battery is used for power supply, which is especially suitable for outdoor and welding occasions where it is not convenient to supply trolley power, so as to prevent the potential safety hazard caused by electric shock caused by the damage of power cable on site.
1.3、The clamping mechanism of welding gun has swinging function, which is suitable for welding wide and thick welds. The positioning accuracy is assured andthespeed of crawling can be kepteven andconstant in both up-slope or down-slope welding, and even operators without professional skills can get good welding results.
2. Features:
1) The DC24V lithium battery is used for power supply, which eliminates the high-voltage power supply of the car body and improves the safety performance of the car.
2) Digital display of digital tube is convenient for adjusting various parameters, small in size, low in center of gravity and easy to carry.
3) The walking speed, swing speed, swing angle, left and right residence time, etc. are precisely controlled by program.
4) The swinging device is controlled by the program, and the swinging device has the functions of left stop and right stop, so as to prevent the phenomenon of insufficient molten pool during swinging welding; At the same time, the weld center can be adjusted during welding to prevent partial welding.
5) The swing function always starts from the center and automatically returns to the center, which is convenient for the second start of welding adjustment.
II. Scope of application:
2.1. Applicable materials: carbon steel, stainless steel, alloy steel and low-temperature steel (materials that cannot be magnetically adsorbed should be equipped with trolley rails).
2.2. Applicable welds: pipe-pipe girth welding, pipe-elbow, pipe-flange, horizontal welding and vertical welding of tank body,Horizontal welding of pipe piles, etc.,
2.3. Applicable pipe diameter: cylindrical pipe ≧ 140mm, inner diameter ≧ 450mm, applicable wall thickness 3-100mm,
2.4. The walking width of the welding trolley should be greater than 300mm, and the gap between the weld base materials should be consistent, otherwise the welding effect will be affected;
2.5. The workpiece (or fixed guide rail) should be made of magnetic conductive material. If there is no magnetic conductivity, the trolley magnet can't be adsorbed on the workpiece, which will cause the trolley to run unsteadily or even fall and be damaged (materials that can't be magnetically adsorbed should be equipped with trolley rails).

one |
Left and right guide wheel parts |
The guide wheel should be close to the vertical plate, fixed and adjusted by screws, and the walking direction of the guide wheel is 5-10mm shorter than that of the rear push, thus playing the role of profiling guide. |
two |
Welding gun clamping part |
Used for centering clamping welding gun and copying welding gun. |
three |
oscillator |
Drive the welding gun to swing in the direction of welding seam, and adjust the swing angle through the electric knob to meet the needs of wide seam width. |
four |
control box |
Used for the electric operation of the trolley. See Article 4.1 Control Box for specific operation contents. |
five |
Magnetic control handle assembly |
The attraction of the magnet is controlled by this handle, with upward separation and downward engagement. (Note: If the trolley is close to the steel plate, the trolley may be automatically adsorbed on the steel plate. Be careful not to insert hands and clothes into it) |
six |
Car body parts |
The main body of the trolley and the traveling device. |
