Hot gas welding, also known as hot air welding, is a plastic welding technique using heat. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. (Welding PVC to acrylic is an exception to ...
On March 22, 2020, Eric Smidt directed Harbor Freight to donate its entire supply of N95 masks, Face shields, and 5/7 mil Nitrile gloves to hospitals with a 24-hour emergency room. In June 2022, Eric & Susan Smidt donated $5 million to the Holocaust Museum LA , which will allow the museum to double its campus in Pan Pacific Park .
Harbor Freight Tools, commonly referred to as Harbor Freight, is an American privately held tool and equipment retailer, headquartered in Calabasas, California. It operates a chain of retail stores, as well as an e-commerce business. The company employs over 28,000 people in the United States, [5] and has over 1,500 locations in 48 states. [6] [7]
Hand welding is a technique in which the weld rod is applied to the joint by the welder directly. This is also referenced as free-hand welding or fan welding. [1] The hot gas torch is maneuvered in one hand to heat both the weld rod and joint surfaces in a pendulum manner in quick succession.

Extrusion welding is an attractive process for applications that take advantage of its ability to weld thick sections quickly. For some applications, especially where there are large geometry parts where more traditional plastic welding methods (such as hot plate welding) is not possible, extrusion welding is the only feasible and cost effect option.
Hot plate welding was first used in the early 1930s for joining PVC. [1] It gained in popularity with the prevalence of polyolefins, which are difficult to adhesively bond. By the 1960s, it was among the most widely used plastic welding methods. [2] Hot plate welding was used for pipelines and appliances as well as injection moldings.
Vibration welding has numerous advantages over other conventional plastic welding processes. Since the heat is created at an interface, the molten polymers are not exposed to open air, preventing oxidation and contamination of the weld during the process. No filler material is required, and when welding components of the same material the joint ...
