NFC Cards – LORCH’s latest innovative technology breaks new ground
LORCH NFC cards allow the welder not only to quickly enter the welding parameters he needs, but also offer an entirely new and efficient approach to quality control.
Today is a new time in industrial welding
LORCH industrial machines offer an affordable entry into the newest technologies and are designed to be easily upgradeable with improved software processes as and when needed.
LORCH Wins 2018 Welding World Award
In Europe, the UK Welding Industry holds an awards evening every 2 years. In March 2018, LORCH was nominated for and won the “Best New Welding Product Supplier” with MICORMIG & NFC products.
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?
Design of Structural Fillet Welds
The strength of a fillet weld is based, in the design, on the design of the throat thickness and effective weld length.
