We have had focus on robotic arc welding since 1974, longer time than any other supplier on the market. This has given us a vast experience of different welding processes in different applications and welding of different types of material. We are very flexible when it comes to using different brands of process equipment, which makes it possible for us to meet all our customers needs when it comes to their preferences. We do also have the experience to help our customers to choose the best process and equipment for their specific application.
Single wire welding
This type of applications are normally welded using solid wire or metal flux cored wire.
The Weldguide seam following sensor is used in most applications both due to the tolerances of the workpiece and also since weaving is the natural way to carry out the welding.
A touch sensor is also used in most cases to find the weld start position.
We are in many cases using the CMT process for welding of thin material. CMT stands for Cold Metal Transfer and is a process developed by Fronius.
The wire movement is incorporated into the process control, where heat is inserted only very briefly. Metal transfer takes place with barely any flow of current.
TIG welding can in some applications have an advantage, but is in many cases replaced by the CMT process.
The TIG process (as well as CMT) can also be used for preventive clad welding on surfaces for corosion protection or in order to obtain a hard surface.
Twin wire welding
This is a high productive welding methode for workpieces with long straight welds in thick material.
With TimeTwin, controllable digital power sources working totally independent – with two separate filler wires – in just one gas nozzle and in a common weld pool.
The CMT process can with advantage be used for welding of aluminium up to 3-4mm thickness, depending on the shape of the weld and material.
The application in this case is tube to tube welding where the workpiece is turned during the welding process in order to get a good weld position.
This is an example of welding of thin stainless steel.
The tooling is very important as well as toleranced of the workpiece in order to achieve a high quality product.
