Microwave energy storage welding

How does Microwave welding work?

Microwave welding is a form of electromagnetic welding using a radiation frequency of 2.45 GHz. Most thermoplastics do not experience an immediate temperature rise when irradiated with this frequency of radiation. This technique normally works by placing a microwave energy absorbing material, in the form of a gasket, at the joint interface.

Is Microwave welding a sustainable process?

Microwave processing of materials has emerged as one of the environmental friendly process in the sustainable manufacturing sectors . In an effort to develop unconventional joining technique to meet the new challenges, microwave welding has been identified as one of the most potential technique.

Can microwave be used in the processing of metallic material?

The application of microwave in the processing of metallic material is relatively a new development in this area.

Which material is used for Microwave welding of nonpolar thermoplastics?

For nonpolar thermoplastics, a microwave absorbing implant is required. The most widely used implant material for microwave welding of plastics is polyaniline (PANI). Similar to semiconductors, PANI conducts electricity through doping with an aqueous acid such as HCl.

Can microwave energy be used to melt bulk metals?

Researchers have succeeded in joining ceramics and composites by microwave, moreover, the joining of bulk metals through microwave energy have been on progressing stage. Melting of bulk metals by microwave such as stainless steel, copper and aluminium was reported in the year 2006.

Which plastics are suitable for Microwave welding?

Polar plastics with high degrees of branching are more suitable than plastics with linear chains. For nonpolar thermoplastics, a microwave absorbing implant is required. The most widely used implant material for microwave welding of plastics is polyaniline (PANI).
