Our Company

WITCO Inspection and Testing Corporation (formerly Welding Inspection & Testing Corporation – WITCO) was organized and registered in July 1991 to provide special services in the field of Welding, Nondestructive Testing, Quality Control and Inspection. The company’s main business revolves around the expertise of its Founder and President MARCELO B. VILLANUEVA whose qualifications and experiences were obtained through over twenty years in the Steel Construction and Testing Industries.

Welding and Quality Control in Steel Construction Projects are two (2) major activities, which have to be properly planned and managed to maintain project costs and schedules. Many projects suffer financially because of inappropriate welding design and specifications; delays are incurred due to lack of welders and/or unqualified welders and supervisors. Inaccurate interpretation of welding specifications as well as the use of inexperienced QC/NDT personnel had in many occasions unnecessarily increased the cost of construction. These problems can be avoided if these activities are handled by an experienced professional group.

Expertise in Welding and Quality Control unfortunately are difficult to find in the local market today primarily because of the manpower drain to the highly lucrative overseas markets. Traditional users of these manpower such as big construction companies and industrial plants cannot maintain adequate pool of these manpower because of uncompetitive pay rates.  They cannot easily increase their pay scales just for this select group without inviting complaints from personnel of other disciplines. It seems that the only workable solution to this problem is to let these activities be handled by a specialized group through a subcontracting arrangement.

Aware of these serious problems facing the local construction industry, WITCO has organized itself to train, qualify, motivate and maintain a pool of highly trained and qualified personnel in welding and quality control to be able to respond to the growing demand of industries.
