Industry 4.0 – Data Management in Welding
Digitizing data, the downloading, sharing, and analyzing of it is a cornerstone of Industry 4.0. What does that mean for welding workshops?
LORCH Operating Systems
The range of LORCH Mig welding machines is a good example of where synergic control is heading in the Industry 4.0 era.
Time – the single biggest cost in welding
TIME is the single biggest cost in welding. This is particularity relevant in NZ as we are increasingly competing on a global basis against manufacturers and fabricators from countries with low labour costs.
Combatting the lack of skilled welding staff
Highly skilled welders can still experience weld flaws, particularly when getting used to new equipment, or under pressure to meet deadlines, however, more often than not the issue of weld defects boils down to a lack of skilled staff.
Metal Cored Wires vs Solid Wire
Productivity improves with increased deposition rates and higher travel speeds, combine this with the minimal spatter and lack of clean up required.
How to calculate welding consumption
Diagrams for a quick estimation of the consumption of welding consumables for welding ferritic steel, butt joints and fillet joints.
KOBE Gas Shielded Metal Arc Welding Essentials Booklet
The quality of weldments made by GSMAW is markedly affected by the welding parameters set by a welder or a welding operator.
Stress Relief Cracking
PWHT relieves residual stresses, remove diffusible hydrogen, and temper hard transformation microstructures of the weld, preventing brittle fractures.
Porosity in Welding
Porosity refers to cavity-type discontinuities or pores formed by gas entrapment during the solidification of molten weld metal.
Hot Crack: How it occurs and how it can be prevented
Hot crack can be defined as cracking formed at high temperatures near the solidus of the metal, where the metal has coherence but is completely brittle.
Hydrogen Cracking – Diffusible Hydrogen and how to avoid it
Hydrogen cracking can occur when welding carbon and low-alloy steels. The potential for hydrogen cracking in the weld metal and HAZ depends on their composition.
Downhill Welding
What advantages are there in downhill welding and how should it be used, compared with uphill welding in GMAW and FCAW?
