Welder Training and Certification
Welder Training and Certification utilizing (SMAW) Shielded Arc Welding, (FCAW) Flux Core Arc Welding, (GMAW) Gas Metal Arc Welding and (GTAW) Gas Tungsten Arc Welding on Plate or Pipe on diverse metal such as Carbon steel, Stainless, Aluminum, and Hastelloy metals. Our classes are tailored to the individual needs whether the student is novice, beginner, intermediate or advance skill welder. Practical test administered on 3G and 4G for plate per AWS D.1 or AWS D1.5. Furthermore, a pipe practical test is taken on the 6G or 6GR position on 3” or 6” diameter pipe or tubing using SMAW or GTAW welding process. Classes are also offered for Iron workers working per AWS D1.8 who will be working on moment connections where welding is Demand Critical, whereby the weld joins the bottom beam flange to the column flange and the weld must be made through a beam web weld access hole.
ULTRASONIC TESTING
Ultrasonic Testing (UT) is a non-destructive testing (NDT) technique based on the generation of ultrasonic waves in the object or material tested. In most common UT applications, short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz, and occasionally up to 50 MHz, are transmitted into materials to detect internal flaws or to characterize materials. Ultrasonic testing is often performed on steel and other metals and alloys, and is used in many industries including steel, stainless and aluminum construction, metallurgy, manufacturing, aerospace, automotive and other transportation sectors.
Here at AGUIRRE INSPECTION SERVICES, INC. we have in hand certified and experienced UT technicians to accommodate your inspection requests. Our technicians are not only equipped to detect a flaw in a test object, but are also able to provide a wide range of details on the flaw including depth, length, severity and size.
Penetrant Testing
Penetrant Testing (PT) is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all ferrous and non-ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability.
Liquid penetrant inspection is a nondestructive testing method that reveals surface breaking flaws by bleed out of a penetrating liquid colored with a visible or fluorescent dye from the flaw. The technique is based on the ability of a liquid to be drawn into a “clean” (in other words, unobstructed) surface breaking flaw by capillary action. After an appropriate period of time for penetration has lapsed, called the “dwell time,” excess penetrant on the surface is removed and a developer applied. The developer acts as a blotter and draws the penetrant from the flaw to reveal its presence. Penetrants with a visible dyed added (color contrast) require sufficient white light to ensure proper inspection, while penetrants with a fluorescent dye added need to be used in darkened conditions with an ultraviolet or “black light”. This method is used to inspect a variety of product forms including castings, forgings, and weldments.
Our certified staff of NDT professionals provide quality inspection services for a broad range of industries. Liquid Penetrant Testing services are offered in field locations and/or labs.
Magnetic Particle Inspection
Magnetic Particle Inspection (MT) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferromagnetic materials such as iron, nickel, cobalt, and some of their alloys. The process puts a magnetic field into the part. The piece can be magnetized by direct or indirect magnetization. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).
AGUIRRE INSPECTION SERVICES, INC. has skilled technicians with many years of experience in performing quality MT services and are Level II or Level III qualified.
Certified Welding Inspector
Certified Welding Inspector (CWI) is a specialized branch of inspection and deals with AWS, API and ASME code compliance. Knowledge of metals and consumables and their compatibility within the code allows for greater quality of inspection.
AGUIRRE INSPECTION SERVICES, INC. has established a core staff of competent and specialized inspectors to provide fast and accurate inspection in all code areas to service your varied and specialized needs. We perform visual inspections in a variety of fields, including: welding inspection, on site surveillance & quality control during welding, manufacturing, and repair phases of production. We are capable of testing to any code or standard and are ready and able to work in any industry or environment.
Bolting Inspection
AGUIRRE INSPECTION SERVICES, INC. our Bolting Inspectors verify that the nuts, bolts, and washers are the right type and in good condition as required in the plans and specifications. During the installation of high strength bolting, the bolts are checked for required torque. Certification test results for nuts, bolts, and washers are checked. Verification of the calibration for the torque wrench is checked and a calibration device is used to check the required bolt tension. Bolts with the required number specified by the engineer are checked at random and then marked with a date when completed. We also initial the connection and the test bolt.
Fireproofing Inspection
AGUIRRE INSPECTION SERVICES, INC. can assist in maintaining the structural integrity of your Fireproofing systems. The fireproofing systems within an operating facility are critical to the emergency protection of equipment support systems and exposed equipment in the event of a fire. The fireproofing serves to limit flame spread due to its low thermal conductivity. Our technicians look at the threat potential when assessing the systems, including large spill, high temperature and high-pressure dangers. We identify issues before they become a potential liability to plant personnel safety, operations and the environment.
Epoxy Inspection
AGUIRRE INSPECTION SERVICES, INC. provides Epoxy Inspection for commercial and residential projects. Epoxy is used to embed hold downs and anchor bolts into existing concrete for shear walls and seismic strength. Epoxy is also used to “anchor in” threaded steel rods from existing concrete to a steel base plate for structural columns. These threaded rods are secure in place by epoxy into existing foundations, slabs or walls and are used for interlocking the old existing walls and foundations to the new expansion. Special Inspection is required depending on the engineer’s design and can subsequently be required in certain cities. We check placement of epoxy per plan for location, type, date and the condition of percussion hammer drilled holes. We also check the cleanliness of holes, observe the epoxy mix, placement and installation of rebar and all threads or hold-downs
