Food and beverage producers regularly employ dry ice blasting for cleaning and sanitizing equipment. The sanitizing capabilities of C02 blasting are even more relevant to food and beverage and many other types of operations during the coronavirus pandemic. Disinfect, deep clean and sanitize your production environment with one of the most effective tools available. Dry ice blasting is proven on microbial decontamination including: listeria, e-coli and salmonella on contact. Take advantage of downtime to address cleaning maintenance, enhance industrial hygiene practices, and decontaminate production equipment.

In welding, like in many other manufacturing and fabrication processes, the process is not complete until the necessary post-processing has been carried out. Post-weld operations are usually performed for reasons such as improving mechanical properties, relieving stress, and improving aesthetics. The two most common Post-weld operations are Post-Weld Heat Treatment (PWHT) and Finishing.

Post-Weld Heat Treatment

During welding, the welded materials are exposed to very high temperatures that can cause micro-structural changes in them. Also, residual stresses build up in welded materials when they are allowed to cool naturally.  If left unaddressed, these stresses and structural changes can severely compromise the mechanical properties of a material and can lead to failure during use. To prevent this, PWHT is required for welded parts. There are two major types of Post-weld heat treatment and they are as follows.

If you’re new to welding, you may be wondering if it’s possible for you to weld aluminum to steel. Welding “like-to-like” metals like steel-to-steel and aluminum-to-aluminum is usually very straightforward. However, when you try to weld together two very different metals like aluminum and steel – such as two components manufactured by tube laser cutting – things can get a little bit more complicated. So, is it possible to weld aluminum to steel? What are your options for doing so? Let’s discuss everything you need to know.
