I have researched all WABO (Washington Assoc. of Building Officials) documentation that I have access to and require your help. I am not able to find any information, allowing or dis-allowing, the use of any types of manually applied flux during testing (27-13.11.4 specifically). My question is can I allow my employees to utilize SOLAR FLUX type B, which conforms to the requirements of United States Military Specification MIL-F-7516B, classes 2 and 4, during their testing for WABO Certification. The compound is applied to the joint area prior to welding to shield the BACK of the weld joint from oxygen, dissipate heat and unwanted oxides, and to clean the surface of the metal. The compound is utilized both in the shop and in the field for all pipe welds, where internal access to the joint is not possible.
Thank you for your help with this matter
