In Addition to being a supplier of brazing and soldering products and services, we are also a complete source for technical information and assistance. Lucas-Milhaupt has chemists, metallurgists, and engineers on staff whose primary job function is to provide technical support for our customers. Services offered include the following services below.
Q:
Can stainless steel be brazed in vacuum below a temperature of 1700° F?
A:
Stainless can not be vacuumed brazed in at a temperature below 1700° F because of the possibility of chrome-oxide formation which will prohibit the flow of the filler metal alloy on the stainless steel. A brazing temperature of at least 1750° F is usually recommended in vacuum for stainless steel. If the stainless steel is nickel plated it can be brazed at temperatures lower than 1700° F.
Q:
What alloy is recommended for brazing copper to copper?
A:
In most cases, when brazing copper to copper in air conditioning and refrigeration service, one our Sil Fos alloys would be recommended. The phosphorous in the alloys allow the Sil Fos group to be self fluxing when brazing copper to copper which eliminates the use of a separate flux.
Our technical support staff assists customers in solving their brazing and soldering problems by recommending appropriate alloys and offering alternatives for their applications. This is accomplished through test brazing of customer components, examination of previously brazed assemblies, and through feasibility studies which explore the options available and the benefits associated with the proposed solutions.
This involves the examination of a customer's entire material joining operation by a member of our Technical Service team. Upon completion of the audit, a written report is furnished, offering recommendations and other cost savings options.
We offer three different seminar options to fit the specific needs of our customers. They include:
"The Fundamentals of Brazing"
"Brazing by Design"
"Road Show"
Technical team members travel to a customer location and provide training to the brazing personnel. This highly customizable program can include a classroom portion where the fundamentals are taught, hand brazing demonstrations and process recommendations.
