FUSING QUALITY WITH EXPERTISE
With a proud 20+ year history of welding all types of metal for various structures, LBD d.o.o. is a company driven by customer satisfaction and service excellence
Headquartered in the city of Rijeka, Croatia, LBD d.o.o. (LBD) offers a wide range of welding, processing, and assembly services for all types of metals.
Having evolved from humble beginnings as a small Croatian business, the company has grown rapidly and is today recognised across Europe for its firstrate services.
With a newly established branch in Trieste, Italy, and a vision for continued expansion, LBD draws on its two decades of industry experience and team of dedicated and qualified personnel to ensure welding excellence every time.
Its staff base consists of engineers, certified welders, structural fabricators, managers, and administrative employees, each of whom are offered comprehensive training and professional development opportunities.
Well-versed in complex projects where various tests of welded joints are required, LBD’s knowledge of the metalworking industry guarantees consistent quality, regardless of the thickness of the material or purpose of the finished product.
FIRST-CLASS SERVICES
Metal inert gas (MIG) and metal active gas (MAG) welding, also known as gas metal arc welding (GMAW), are versatile welding processes that enable fast and efficient results, applicable to various metals.
LBD utilises MIG and MAG alongside two other welding processes, Tungsten inert gas (TIG) and remote exothermic welding (REL).
The method selected depends on the type of material being welded, alongside its thickness and the environment in which it must perform.
Offering a comprehensive range of supplementary services, including magnetic particle testing (MPT), non-destructive testing (NDT), and ultrasonic testing (UT), the company conducts its activities in a workshop fitted with cranes which have capacities of 10, seven, or five tonnes.
It also offers construction services and technical support solutions throughout the entire project life cycle, from the initial design stages to the finished product.
Utilising top-of-the-range 2D and 3D modelling programmes alongside appropriate methods and specifications helps LBD produce a precise and defined final product.
PROJECT OF NOTE
LBD is currently working on the MV-10 BISON (MV-10) demining machine for DOK-ING, a leader in the development and production of robotic and autonomous systems and equipment.
An industry stalwart for over three decades and present in 40 countries, DOK-ING is known for its innovative approach and state-of-the-art technologies, which have earned it a superior status in international markets.
LBD is therefore committed to its responsibility of welding and manufacturing the machinery to a high quality.
A crucial piece of equipment, the remote-controlled MV-10 uses a rotating appendage to detonate landmines at mine sites across the world.
Made entirely of HARDOX 450 steel, the MV-10 benefits from the resilience and endurance of the material, making it ideally suited to operate in challenging terrains.
Proud to showcase its involvement in the development of this product, LBD demonstrates its ability to deliver the highest standards of quality and workmanship.
LBD d.o.o. has a Non-Destructive Testing (NDT) department. NDT of welds and base materials is a critical process used to evaluate the integrity and quality of components without causing damage. It ensures that welds are free from defects such as cracks, porosity, or incomplete fusion, and that the base material meets structural and safety requirements. LBD d.o.o. and its employees are certified in the following NDT methods: visual testing (VT), ultrasonic testing (UT), radiographic testing (RT), magnetic particle testing (MT), dye penetrant testing (PT), holiday test and hardness test. Each of the methods is suited to different types of materials and flaw detection. These techniques help prevent failures, improve reliability, and maintain compliance with industry and state standards.
Visual Testing (VT) is the most basic and widely used non-destructive testing method. It involves
inspecting the surface of welds and base materials with the naked eye or with the help of tools like magnifying glasses, borescopes, or cameras. VT is used to detect surface defects such as cracks, undercuts, porosity, misalignment, and incomplete welds. It is often the first step in quality control and is cost-effective, quick, and easy to perform, but limited to surface-visible flaws.
Magnetic Particle Testing (MT) is a non-destructive testing method used to detect surface and nearsurface defects in ferromagnetic materials like carbon steel. The process involves magnetizing the part and then applying fine magnetic particles (either dry or suspended in liquid). If there are any discontinuities such as cracks or laps, they create leakage fields that attract the particles, forming visible indications. MT is highly effective for detecting surface-breaking flaws but cannot be used on non-magnetic materials like aluminum or austenitic stainless steel.
Penetrant Testing (PT), also known as Dye Penetrant Testing, is a non-destructive method used to detect surface-breaking defects in nonporous materials, both metallic and non-metallic. It involves applying a liquid dye penetrant to the surface, allowing it to seep into any cracks or flaws, then removing the excess and applying a developer to draw the penetrant back out. This creates a visible indication of defects such as cracks, porosity, or seams. PT is especially useful for materials that are non-magnetic, unlike MT, but it only reveals surface defects.
Radiographic Testing (RT) is a non-destructive testing method that uses X-rays or gamma rays to inspect the internal structure of welds and materials. The radiation passes through the component and exposes a film or digital detector on the opposite side. Variations in material thickness or internal flaws like porosity, slag inclusions, or lack of fusion appear as differences in density on the radiograph. RT provides a permanent record of the inspection and is highly effective for detecting internal defects, but it requires strict safety precautions due to radiation exposure.
Ultrasonic Testing (UT) is a non-destructive testing method that uses high-frequency sound waves to detect internal flaws, measure thickness, and evaluate material properties. A transducer sends sound waves into the material, and any reflections from discontinuities - such as cracks, voids, or lack of fusion—are recorded and analyzed. UT is highly sensitive, capable of detecting very small internal defects, and can be performed from one side of the component. It is widely used in weld inspection, corrosion monitoring, and thickness measurement, especially in materials where radiographic testing cannot be used.
Hardness testing is a non-destructive method used to measure a material’s resistance to deformation, typically by indentation. It provides valuable information about the mechanical properties of welds, base materials, and heat-affected zones (HAZ), such as strength and wear resistance.
