The making of 'Laulupuut' welded sculpture

In 2017, it has been 40 years since the inverter power source was developed. We sat down with Tapani Mäkimaa, an original member of the development team, and discussed what makes Kemppi a pioneer in its field, year after year.

We asked two professional welders – Meyer’s Jukka Hahko and Dinolift’s Pasi Laakso – what good usability means in industrial welding.

In the 1960s, there was a huge shortage of professional welders in Finnish growth centers. That is why Keijo Olkoniemi, whose career as a welder has lasted for almost 50 years, trained to become a welder, a profession which has offered him challenges throughout his career. ”I remember when they said at the dockyard in Hietaniemi, Helsinki that you can bring a train full of skillful employees, and we will hire them all,” Olkoniemi says, laughing.

In TIG welding, process development has mainly focused on modifying the current modes in different situations. In practice, this means variations of pulse and AC welding, as well as ignition or tack welding. In the case of pulse welding, the welding machine user has numerous choices, as the adjustment possibilities for these process variations are highly versatile.

Svetsning ABC, Manuell svetsning

Vid svetsning av ferritiska stål, i synnerhet höghållfasta stål, kan magnetisk påverkan bli en verklig utmaning. Detta fenomen uppstår när magnetfält stör svetsbågen, vilket orsakar instabilitet, stänk och ibland gör svetsningen nästan omöjlig.

Manuell svetsning
