WHY FUSION WELDING?

• Weld similar or dissimilar metals.
• Stronger than traditional methods of joining parts because you are creating a true metallurgical bond.
• No annealing of parts.
• No special cleaning or refinishing after welding.
• Much faster.
• Weld to thin materials.
• No drilling or staking.
• No filler materials.
• No electrical resistance at the weld.
• Similar or dissimilar metals.

What are the principals that make fusion welding so easy to use?

Fusion welding is in effect a controlled short circuit. Charged electrolytic capacitors are shorted out through an initiation nib that is either turn formed or headed on the weldable part. This nib serves as a resistance focus for the capacitors discharge. The weldable part is moved at a controlled velocity over a distance of about 3/4 of an inch to the base piece. Upon contact the nib ionizes instantly creating a conductive path for the energy discharge. This high intensity arc melts the surface of the stud and base piece. The following impact joins the two parts in a true metallurgical bond. Heat rise and dissipation is almost instant. This prevents annealing and distortion.

Because the energy, velocity and nib size are precisely predetermined, the welding action is automatic requiring no judgment or operator skills. Since these three variables are controlled, weld output is consistent. And because fusion welding is a surface weld, the thickness of the base part is not a factor in setting weld parameters. With the material being affected only about .002" deep the reverse surface is unaffected.
