L'innovazione
Quanto siamo pronti per il Green Steel?
20 giugno 2021
Il settore siderurgico è senza dubbio uno dei settori con le maggiori emissioni di CO2 e gli effetti di tali emissioni sull’ambiente destano preoccupazione. L’acciaio ad alta resistenza e “verde” può offrire vantaggi sia ambientali che finanziari ai produttori che contribuiscono allo sviluppo sostenibile. Ma quanto siamo preparati al suo utilizzo?

Calculation of heat input in MIG/MAG welding
The new welding procedure test standard, EN-ISO 15614-1:2017, provides recommendations for the measurement and calculation of heat input. In concrete terms, what does this mean for MIG/MAG welding? And how can workshops carry out these calculations in practice?

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.
