Project Number 1

Summary:

Several cleaners have been found to remove the multiple sources of contaminants from the different metal surfaces.

Test Objective:

Improve cleaning of weld edge backer and wire prior to EB weld

Product Use:

weld edge metal band saw blades
Trial Number Date Run Purpose Success Rating
0 09/12/2001 To compare alternative cleaners with two current client supplied cleaners Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
1 09/17/2001 Evaluating previously tested products using gravimetric analysis Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
2 09/17/2001 Evaluating previously tested effective products on second Stubbs rust preventative Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
3 09/18/2001 Evaluating previously tested effective products on second Stubbs rust preventative Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
4 09/18/2001 Evaluating previously tested effective products on third supplied contaminant Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.
5 09/20/2001 Evaluating previously tested effective products on third supplied contaminant A follow up test, usually based on company input.
6 11/05/2001 To evaluate ultrasonic energy with successful cleaners. A follow up test, usually based on company input.
7 11/07/2001 To compare ultrasonic and immersion cleaning. A follow up test, usually based on company input.
8 11/14/2001 To evaluate ultrasonic cleaning on supplied parts Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.
9 11/20/2001 To compare ultrasonics and immersion cleaning at shorter cleaning time A follow up test, usually based on company input.
