7Robot Sumbu dalam Otomatisasi Pengelasan: Studi Kasus Nyata dan Contoh ROI

Tantangan Inti dalam Otomasi Pengelasan

“Kami memiliki jahitan panjang untuk dilas. Setiap reposisi membutuhkan waktu 20 menit. Kami kehilangan waktu berjam-jam setiap hari.”

This is the most common problem I hear from manufacturers in heavy fabrication, tank manufacturing, and shipbuilding. Solusinya?A 7th axis robot welding system.

In traditional welding setups, stationary robots are limited to a small working envelope — typically 1.5 ke 3 meter. When workpieces exceed this length, operators must stop production, reposition the part, and restart the weld. Setiap reposisi membutuhkan waktu 15-20 menit. Over a full shift, these interruptions can add up to 2-3 hours of lost productivity.

A 7th axis Robot solves this problem by allowing the robot to travel along a linear track, covering the entire length of the workpiece in one continuous pass. No stops. No repositioning. Tidak perlu menunggu.

Dalam artikel ini, I will sharereal case studiesfrom actual customer installations, provide adownloadable ROI calculator, and show you exactly how much you can save by adding a 7th axis Robot to your welding line.

By the end of this article, you will be able to calculate your own ROI in under 10 menit.

Bagian 1: Why Long Seam Welding Needs a Robot 7th Axis

Long seam welding applications — such asbalok, storage tanks, ship hulls, menara angin, and pressure vessels— present unique challenges that stationary robots cannot handle efficiently.

The Limitations of Stationary Robots

When you try to weld long parts with a stationary robot, you face several problems:

• Limited reach:Most industrial robots have a working envelope of only 1.5 ke 3 meter. Anything longer requires repositioning.
• Multiple repositioning:Each 6-18 meter beam may need 3-5 repositionings. Setiap reposisi membutuhkan waktu 15-20 minutes of downtime.
• Low arc-on time:With all the stopping and starting, tepat waktu (actual welding vs. waiting) drops to only 25-35%.
• High labor cost:You need 2-3 operators per shift just to handle repositioning and fixturing.
• Inconsistent quality:Each time you reposition and restart, there is a risk of misalignment or inconsistent weld parameters.

The Advantages of a 7th Axis Robot

A 7sumbu ke- Robot welding systemeliminates these problems:

• Full coverage:The robot travels the entire length of the workpiece in a single pass.
• No repositioning:Once the part is clamped, the robot does all the moving.
• High arc-on time:With continuous welding and parallel operator tasks, arc-on time jumps to 85-90%.
• Lower labor cost:Satu7robot sumbu ke-th can serve 3-5 stasiun, requiring only 1 operator per shift.
• Consistent quality:The same weld parameters apply across the entire seam.

Wawasan utama:Any welding application where the workpiece exceeds3 meter in length is a perfect candidate forrobot 7th axis welding.

The best industries for this technology include: structural steel fabrication, storage tank manufacturing, pembuatan kapal, wind energy, and pressure vessel manufacturing.

Bagian 2: Studi Kasus Dunia Nyata

Studi Kasus 1: Structural Steel Fabricator in Jiangsu — I-Beam Welding

Pelanggan:Large structural steel fabricator in Xuzhou, Jiangsu Province, Cina. The company has over 300 employees and an annual production capacity of 50,000 tons of steel structures for industrial plants and logistics warehouses.

Masalahnya:The customer needed to weld I-beams ranging from 6 ke 18 meters in length. Their existing setup used 4 stationary welding robots, each serving one station. Between passes, operators spent 15-20 minutes repositioning each beam. Robot utilization was only 32%. The shop floor was crowded, and they were struggling to meet delivery deadlines.

The Solution:We designed and installed a D003 heavy-duty7robot sumbu ke-th system with 25 meters of travel. The track was equipped with metal covers for spatter protection and IP67-rated servo motors for the harsh welding environment. The system was integrated with their existing Fanuc ARC Mate 120iC welding robot.

Hasilnya:

Metrik	Sebelum (4 robot)	Setelah (1 7sumbu ke-)	Peningkatan
Robots used	4	1	-75%
Waktu tepat	32%	86%	+169%
Keluaran harian	24 balok	68 balok	+183%
Operators per shift	3	1	-67%
Investasi	~$380,000	~$72,000	-81%

ROI Calculation:

• Annual labor savings: $120,000 (2 operators at $60k each)
• Annual productivity increase: $180,000 (based on 183% output increase)
• Total penghematan tahunan: ~$300,000
• Periode pengembalian: ~3 months

“We were planning to buy two more robots. Our integrator recommended the 7sumbu ke- larutan. At first, we didn’t believe one could replace four. After three months, the numbers don’t lie. Now our other two lines are being converted.”

— Production Manager, Xuzhou, Jiangsu

Studi Kasus 2: Kapal Tekanan / Tank Manufacturer in Shandong — Longitudinal and Circumferential Welding

Pelanggan:Large tank manufacturer in Zibo, Shandong Province, Cina. Their main products include LNG storage tanks and chemical storage tanks with diameters ranging from 2 ke 8 meter.

Masalahnya:The customer was using manual welding for all tank seams. Each tank required 4 jahitan memanjang (8-15 meters each) Dan 2 circumferential seams (6-25 meters circumference). Total welding time per tank was 22 jam. The rework rate was 18% due to inconsistent manual weld quality. The company was losing bids because their labor costs were too high, and they could not keep up with growing demand.

The Solution:We designed a custom D0037robot sumbu ke-thsystem with 18 meters of travel for longitudinal seams, plus a rotary positioner integrated with the 7robot sumbu ke-th for circumferential welding. We also configured a dual torch setup for simultaneous welding on both sides of longitudinal seams, cutting welding time in half. The system was protected with metal bellows for spatter resistance.

Hasilnya:

Metrik	Sebelum (petunjuk)	Setelah (7sumbu ke-)	Peningkatan
Welding time per tank	22 jam	4.5 jam	-80%
Rework rate	18%	3%	-83%
Keluaran harian	0.8 tank	3.2 tank	+300%
Operators per shift	4	1	-75%
Annual capacity	200 tank	800 tank	+600 tanks/year

ROI Calculation:

• Annual labor savings: $165,000 (3 operators at $55k each)
• Annual rework savings: $144,000 (15% reduction × 800 tanks × $1,200/tank)
• Annual productivity increase: $2,100,000 (600 additional tanks × $3,500 batas)
• Total penghematan tahunan: ~$2,400,000
• Periode pengembalian: ~20 days (0.6 bulan)

“In the third week after this 7sumbu ke- system went live, finance told me it had already paid for itself. We’ve ordered two more systems to convert our other two workshops. I wish we had done this three years ago.”

— General Manager, Zibo, Shandong

Studi Kasus 3: Structural Steel Fabricator in Midwest USA — Heavy Structural Welding

Pelanggan:Heavy structural components manufacturer in the Midwestern United States, serving the construction machinery industry. Their primary products include excavator arms, bulldozer frames, and other large welded assemblies.

Masalahnya:The customer needed to weld excavator arms up to 12 meters in length. Their original plan was to purchase a large gantry system, which was quoted at $380,000 dengan lead time 4 bulan. The gantry would also require a reinforced concrete foundation ($40,000 tambahan), 3 minggu waktu henti instalasi, and specialized maintenance training for their team.

Alternatif yang Kami Usulkan:Instead of the expensive gantry, we proposed a D003 heavy-duty7robot sumbu ke-th system with 15 meters of travel and 3,000kg load capacity. The system was paired with their existing Fanuc ARC Mate welding robot, requiring only a custom mounting plate and software integration.

Hasilnya:

• Investasi awal: $380,000 (gantri) →$62,000 (7sumbu ke-)— 84% lebih rendah
• Waktu instalasi: 3 minggu →4 hari— 80% lebih cepat
• Pekerjaan pondasi: $40,000 →$0(standard floor only)
• Waktu tepat: 38% →86%— produktivitas dua kali lipat
• Keluaran harian: 120 bagian →310 bagian— 158% meningkatkan
• Periode pengembalian:9 bulan

*”Kami siap menulis cek untuk gantry. Integrator kami menyarankan agar kami melihat a7sumbu ke- instead. Saya senang kami mendengarkan. Kami tidak hanya menghemat $300,000, but we were up and running in four days instead of a month.Our floor track system changed how we think about automation.“
