Certifying a Machine
When a new tool arrives on-site, it should be tested for proper welding operation prior to being
utilized on a project. All tools are tested at the factory prior to delivery, but conditions of
delivery cannot be controlled and equipment could be damaged.
Several joints should be prepared on the tool of varying pipe diameters. The quality of the joint
should be within the parameters of the above manual. In addition to the above manual, several
other checks can be done as follows:
1.
After the heat soak time is complete, when making a joint, the pipe should
be pulled apart and the heating element should be removed. The pipe ends
should be inspected for full even melt 360 degrees around the ends. This
will help to verify the heat temperature and welding parameters.
2.
After the heat soak time is complete, when making a joint and the pipe is
rejoined together, a narrow object (such as a pencil or finger) can be placed
inside the pipe without touching the joint. The operator should be able to see through the
molten material for a few seconds and see the object. This will verify the welding pressure.
If the operator cannot see the object and has joined the material together without receiving an
error, the pressure utilized to make the joint may be too great and the tool may need to be
recalibrated. Also verify correct welding parameters are set on the tool.
All joints should be as described in Sections: Bead Formation and Bead Sizing. When receiving a
new tool and testing it for operation, questionable joints may be returned to Asahi/America,
Inc. for evaluation.
