Bridging the Gap

Project - Bogibeel Bridge, Assam - HCC

 

When discussing infrastructure in India it is hard not touch on the topic of bridges. There are so many bridge construction projects underway or in the planning stages as it is one of the India’s most important industries.

 

The Bogibeel Rail - Road bridge is one such project that recently was completed on December 25th, 2018. It is a double decker bridge with a two line railway track on the lower deck and a three lane road on the upper. With the title of India's longest road and rail bridge at 4.95km. It was important that the construction of the bridge be of the utmost quality. As the first fully welded rail and road bridge over the Brahmaputra the choice of welding equipment was paramount to the success of the project.

 

The Bridge is a combination of fully welded steel trusses and concrete. It spans 125m and has strong heavy box sections throughout. It was difficult to turn and position the girder boxes at the construction site while welding the joints so the company in charge of construction, HCC chose to implement GULLCO’s welding automation carriages to complete the GMAW welding process. By incorporating welding automation such as the KAT® all position welding carriage, HCC was able to produce UT and MPT quality welds on site without having to worry about manipulating or turing the heavy structures. They were able to achieve this because GULLCO’s carriages are designed for field welding applications and the equipment can be installed directly onto the structure using a modular system of track and mounting devices (most commonly magnets). The KAT® Oscillator carriage with Rigid track was used to weld these butt joints in vertical and overhead positions. The carriage is a portable, light-weight and is easily mounted or repositioned other weld joints by one welder. The use of these carriages removes the need of skilled welders and eliminates weld defects and costly repair work as it ensures high quality and repeatable welds at increasing productivity through consistent arc on time. Mechanised welding makes the planning more predictable, and, since it is less strenuous for the welders, helped this project meet its production deadlines and save money through welding efficiency which can only be achieved through the use of automation.

 

GULLCO’s KBM-28 bevelling machines also played a vital role for edge preparation of the plate used in the box sections. At a thickness  of 8mm to 50mm. The bevellers produced clean machined bevels with no thermal distortion or heat affected zone. This meant that after the material was bevelled it was immediately ready for welding. Completing these bevels at a speed of 2m/min this cold shearing method of plate preparation is the most time efficient way of bevelling the plate and is 4 to 10 times faster than cutting or grinding and improves work environment by reduce noise and vibration.

 

As more and more infrastructure projects like these get underway and the competition for these projects becomes increasingly more competitive companies will have to adopt automation into the planning phase in order to reduce cost and increase price competitiveness when bidding against others. The Bogibeel bridge is another great example of how the effective use of welding and cutting automation solutions can give you the productivity and quality necessary to meet production deadlines and reduce costs.

The Water Taxi

During a trip to India there was an opportunity to travel to Bangladesh to visit Shipyards. Western Marine in Chittagong City gave us an invitation to discuss welding automation and how to implement improved productivity solutions in their shipyard. Upon our arrival we were told that the only way to the yard was by water taxi which was provided by Western Marine.

As we got closer to the yard, however, the low water levels made it impossible for the water taxi to go any further. We would have to make use of a row boat to get us the last 500 meters to the dock. When we arrived we were greeted like dignitaries. One of the most memorable journeys to a shipyard I have experienced.

Their challenge was that their manpower was at the maximum for their size and were looking to automation to increase the productivity of the existing manpower they had. After walking through the shipyard we identified some bottle necks in their production and found two areas where great improvements could be made. We sold them some muti-pass weld oscillation carriages and track automation to suit their needs. The great thing about this solution for them was that the KAT® Oscillator could be used for a variety of different applications and could be equipped for cutting applications if necessary. By automating the welding process great improvements to the weld quality were achieved eliminating much of the rework as well as minimizing stops and starts which vastly improved the arc on time of the welding process. These two improvements alone helped the shipyard to reach their goals and get back on schedule.

Distributors Go the Extra Mile

Marathon One of the things that separates Gullco from other companies in the industry is our Distribution network. We have worked hard over our 60 years in business to build great relationships with companies around the world who have the same passion for welding as we do. One of these companies is Stuch Schweißtechnik in Germany. Like many of our distributors the employees at Stuch have become our friends and their commitment to Gullco extends far beyond sales.

Every year Gerhard Stuch (Owner) runs in the local semi-Marathon of his town of Bonn. Gerhard has recruited members of his family to run with him and it has become a yearly tradition. Special congratulation to his grandson who finished first for his age category! Marathon Finish Running in a Gullco orange outfit complete with Gullco hat, Gerhard shows just how committed he and Stuch Schweißtechnik are to the company. It is special to think that we have built such a great relationship that companies like Stuch are willing to represent Gullco in their personal time. This is just one example of how our distributors have a growing commitment to our company and our products. Whether it is making a service call or demonstrating our products. Local distributors like these have become a pinnacle element in Gullco’s ability to serve the world welding market with automation solutions, parts and service. Check out our distributor page!

Four Pigs and a Penstock

4 Pigs

Welding automation sales can take you to some very unique places. World travel and remote locations become common place, strange food and great stories a part of everyday life. This story takes place 8900 ft. above sea level in the Andries mountains near Huanuco, Peru. map

 I happened upon these 4 pigs while ascending the mountain switchbacks on my way to meeting some fellow Gullco employees at the site of a 6 meter diameter penstock. The site was part of a project being constructed to divert water for the purpose of power generation. Well underway, the setup of the KAT® weld oscillation carriage was being used to produce continuous welds, 4 meters long, in the vertical position. The customer was a large Brazilian contractor and I spent the night in the camp along with the 600 employees living at the work site by the river.

It is rewarding to know that Gullco is playing a part in improving the productivity in such an important hydro electric project. Once complete the plant will provide thousands of rural Peruvians with power. Weld automation really does bring it all together.
