Energy storage welding of railings

How to weld a railing?

Rather done in pipe or tube steel the majority of welds on a railing are fillet welds anyway. Since there is an overlap in the Codes (D1.1 goes down to 1/8 while D1.3 goes up to 3/16) a simple fillet weld break test will usually cover almost all railing welds. And you can do it with pipe to plate with a 1 1/2" pipe.

Why is welding important in rail maintenance?

Welding is a critical process in rail maintenance and an important cost and time factor for maintenance companies. In view of the increasingly complex require-ments made on track construction, in particular with regard to speed as well as process and work safety, there is no way around optimisation of the welding pro-cess.

What are the advantages of robotic welding pending on rail type?

A reduced preheating temperature, de-considerable improvement in safety, The high level of process safety of robotic pending on rail type, of about 200°C to productivity and economic efficiency – welding was already proved in other in- 300°C and the low local introduction of provided it is applied correctly.

How are welding parameters recorded?

All welding parameters, such as welding current and voltage, wire feed and gas flow as well as the energy required, are recorded via defined controls and, if required, combined with an active control which further improves the welding process and consistently avoids scrap and mistakes.

How does a welding gang work?

A three-person permanent-way gang cuts out a piece of rail and then resurfaces it in sever-al layers. At the end the sur-face is finished by grinding. A welding robot in a container above the damaged section carries out all the tasks. It is operated by only one member of staff.

Why do we need a weld monitoring system?

Monitoring considerably less material. The costs per potential is high; the handling of mol- of the process and weld parameters en- weld, without taking account of the shorter ten steel and the usually unergonomic sure the integrity of the automated work turnaround time, are approximately 1 to posture of the welder leads to an in- sequence.
