With the introduction of RoHS legislation, manufacturers of electronic appliances have had to adapt their welding systems to use lead-free welding alloys. Because the new alloys require a higher fusion temperature, they are also more liable to oxidation. One way of preventing this is to direct a flow of nitrogen over the welding process. Both wave welding and reflux oven welding are affected by this phenomenon.

Solution

Claind’s basic solution for combating weld oxidation is to install a standard nitrogen generator to deliver gas of adequate purity for the welding process and a nitrogen accumulator of suitable size to cover the requirements of intermittent operations. All Claind nitrogen generators can be used in welding processes according to the plant configuration.

Benefits

- Economical: between 70% and 300% savings in the cost of nitrogen
- Independence from compressed and liquid gas suppliers
- Flexible modular system, expandable in time without replacements
- Operational safety, thanks to the fact that the nitrogen is generated at low pressure and is only stored in small quantities
