All-Position Pipeline Automatic Welding System

The fully automatic pipeline welding system consists of a welding tractor, power source, orbit, welding torch, and welding cables.

Welding Tractor (Model: M-506)

This system is suitable for field automatic welding of pipelines in such industries as petroleum, petrochemical, natural gas, offshore oil, marine engineering, shipbuilding, and urban water supply pipeline, and on on.

Key Features:

1. The track system enables simple and rapid installation and removal, with operational integrity unaffected by work piece temperature.
2. Five welding modes accommodate various welding scenarios and requirements.
3. Motorized adjustment allows real-time vertical and horizontal positioning of the welding torch.
4. An integrated anti-fall safety mechanism prevents accidental detachment.
5. In pipeline automatic welding, operators can set customized welding parameters for up to 18 individual zones

6.The low-speed high-torque drive system can delivers 30 kg of torque at travel speeds as low as 50 mm/minute.

7. Torch’s center can be set freely, left and right oscillation speeds can be adjusted separately

• Can weld stainless steel,high strength steel, high alloy steel, low alloy steel, carbon steel, various nickel (iron, cobalt) based alloys well
• With group controlinterface

 

Root welding:

Vertical downward welding, suitable for welding various pipelines in petroleum, chemical and other industries

Technical features

1. Can take the place of TIG welding to do backing welding, and its speed is 3-4 times of TIG welding
2. Heat input can be accurately control, similar to TIG welding
3. Few spatter, seam beautiful
4. In root welding, the welding meat is smooth, and backside of welding seam will not be sunken, but bulged
5. Suitable for metal-cored wire and sold wire
6. Weld seams with misalignment below 5mm can be perfectly root welded.

 

Hot welding:

Hot welding adopts high-speed pulse vertical downward welding

Technical features:

1. Deep molten depth, high speed, no edge biting, almost no spatter welding
2. Suitable for 1.0 1.2, 1.6 solid core and flux cored welding wires, arc burns stably in low current welding
3. High speed pulses automatically form compressed arcs with high currents, resulting in greater melting depth; The groove can be changed from the traditional 60 ° to 30 ° or 40 °, greatly improving welding production efficiency and reducing costs.
4. In high current (such as 300A)welding, the penetration depth of high-speed pulse welding is 33% deeper than that of CO2 DC welding; and 45%deeper than argon-rich (80% Ar+20% CO2)  welding;
5. In high current (such as 300A)welding, the speed of high-speed pulse welding is 30% faster thanthat of CO2 DC welding.
6. When welding with flux cored wire, the penetration depth can be deeper;  arc stirring effect can be strengthened to further avoid slag inclusion and pores. At the same time, in low current welding, arc burns more stable, and there is no droplet balls at the end of wire.

 

Fill welding:

Filler welding adopts high-speed pulse vertical downward welding, with high welding speed, good fusion, and low heat input.

Technical features:

1. Also adopthigh-speed pulse welding like hot welding, only the current and voltage are different.
2. The weld seamwill be U-shaped, which is beneficial for quality control of the next weld seam

 

Cover welding:

Cover welding adopts high-speed pulse vertical upward welding or root welding.

Technical features:

1. The weld seam is not too high, the fusion of the weld seam is good, and the shape is beautiful.
2. Almost splash free, secondary cleaningis not needed
