For induction welding, the energy source is an electromagnetic field for dielectric welding, the energy source is an electric field of high frequency. [Pg.525]

Plastics that are readily bonded with induction methods include aU grades of ABS, nylon, polyester, polyethylene, polypropylene, and polystyrene, as well as those materials often considered more difficult to bond such as acetals, modified polyphenylene oxide, and polycarbonate. Reinforced thermoplastics with filler levels up to 65 percent have been joined successfully. Many combinations of dissimilar materials can be bonded with induction welding processes. Table 8.5 shows compatible plastic combinations for electromagnetic adhesives. Thermoset and other nonmetallic substrates can also be elec-tromagnetically bonded. In these applications the bonding agent acts as a hot-melt adhesive. [Pg.527]

Important determinants of bond quality in induction welding are the joint design and work coil design. Proper coil and joint designs are essential for good welds and determine whether or not electromagnetic welding can be used successfully. Other parameters... [Pg.480]
