The essential guide
A robot typically works between two or more work stations. This means that during
the robot welding cycle the operator is unloading a welded assembly and then loads
new components to a welding fixture. Because there is less handling compared to a
manual weld cycle the robot achieves much higher levels of arc-
The robot has a very high repeatable accuracy (± 0.04 mm) and excellent path following accuracy. The robot presents the welding gun at the correct welding angle, welding speed and distance. The high level of integration to the welding equipment ensures that optimum welding conditions can be used for each and every joint. The end result is consistent high quality output, day in day out, year in year with reduced cost for rework, scrap or removal of weld splatter.
It is up to the judgment of a manual welder to weld to the correct standard, but often the weld is oversize. A robot however, always welds to the correct length and size of weld that it has been programmed to produce. This means that some potential savings in wire consumption can be made. If for example a manual welder welds a 5 mm fillet, where only a 4 mm fillet is required, the savings in welding wire alone will be a staggering 36%!
In recent years it has become increasingly difficult to employ manual welders. There tends to be a certain amount of staff turnover and this of course carries a cost for recruitment and training. When labour is an issue companies often find themselves working overtime or having to employ additional contract labour to meet demands and this can have a serious impact on production costs. If products cannot be supplied to the end customer, penalties may be incurred or future business may be at risk. Whilst there will always be a requirement for manual welding, companies that invest in robotic automation are much less dependent on manual welding.
A robot welding system addresses health and safety issues associated with dangerous
welding fumes and exposure to arc-
The robot can be used to weld many different products and allows companies to consider Just In Time production. By reducing work in progress and stock levels, savings can be made due to fact that less value is added to stock levels in terms of labour, transport and storage costs.
Compared to the same output from manual welding bays the robot requires less floor space.
