How Ready Are We for Green Steel?
20 czerwca 2021
The steel industry is without a doubt one of the highest CO2-emitting industries and its effects on the environment raise concerns. High-strength and “green” steel can offer both environmental and financial benefits for manufacturers that contribute to sustainable development. But how ready are we to commit to it?

Welding in arctic conditions
Today, Arctic areas are attracting much attention due to the large oil and natural gas deposits located there. As much as 13% of the Earth's unexploited oil reserves and 30% of natural gas reserves may be located in Arctic areas. The energy industry's largest projects to build gas and oil distribution networks are essentially based on steel construction and welding technology.

Kemppi's advanced welding processes: TIG and stick welding (MMA)
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.

Magnetism in welding: how to deal with magnetic blow
When welding ferritic steels, especially high-strength grades, magnetic blow can become a real challenge. This phenomenon occurs when magnetic fields interfere with the welding arc, causing instability, spatter, and sometimes making welding almost impossible.
